hello friends today we will learn how to Compress and Decompress any file in Linux .Linux Server in File compression very powerful we can can Compress any file through many methods here i show you some Powerful method .You just follow simple step<\/p>\n

\"compress<\/p>\n

Step 1.here i create some text file and then i compress and compress through TAR method
\n [root@localhost ~]# touch a1.txt<\/strong><\/span>
\n [root@localhost ~]# touch a2.txt<\/strong><\/span>
\n [root@localhost ~]# touch a3.txt<\/strong><\/span>
\n [root@localhost ~]# touch a4.txt<\/strong><\/span><\/p>\n

<\/p>\n

Step 2 here i provide every file 40 MB size<\/p>\n

[root@localhost ~]# dd if=\/dev\/sda if=a1.txt bs=2MB count=20<\/strong><\/span>
\n0+0 records in<\/span>
\n 0+0 records out<\/span>
\n 0 bytes (0 B) copied, 3.0118e-05 seconds, 0.0 kB\/s<\/span>
\n[root@localhost ~]# dd if=\/dev\/sda of=a1.txt bs=2MB count=20<\/strong><\/span>
\n20+0 records in<\/span>
\n 20+0 records out<\/span>
\n 40000000 bytes (40 MB) copied, 0.0749134 seconds, 534 MB\/s<\/span>
\n[root@localhost ~]# dd if=\/dev\/sda of=a2.txt bs=2MB count=20<\/strong><\/span>
\n20+0 records in<\/span>
\n 20+0 records out<\/span>
\n 40000000 bytes (40 MB) copied, 0.123504 seconds, 324 MB\/s<\/span>
\n[root@localhost ~]# dd if=\/dev\/sda of=a3.txt bs=2MB count=20<\/strong><\/span>
\n20+0 records in<\/span>
\n 20+0 records out<\/span>
\n 40000000 bytes (40 MB) copied, 0.144952 seconds, 276 MB\/s<\/span>
\n[root@localhost ~]# dd if=\/dev\/sda of=a4.txt bs=2MB count=20<\/strong><\/span>
\n20+0 records in<\/span>
\n 20+0 records out<\/span>
\n 40000000 bytes (40 MB) copied, 0.104576 seconds, 382 MB\/s<\/span><\/p>\n

Step 3 now we check our file
\n[root@localhost ~]# ls -lh<\/strong><\/span>
\ntotal 156.0MB<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:27 a1.txt<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:27 a2.txt<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:27 a3.txt<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:37 a4.txt<\/span><\/p>\n

tar -cvf compression\u00a0<\/strong><\/h1>\n

Step4- so let we will combine all file with \u00a0tar compress<\/p>\n

[root@localhost ~]# tar -cvf alltxt.tar a1.txt a2.txt a3.txt a4.txt<\/strong><\/span><\/p>\n

(Note- if we have large of number file then we will use (*) \u00a0 like this [root@localhost ~]# tar -cvf alltxt.tar .txt* \u00a0) \u00a0<\/strong>
\na1.txt<\/span>
\n a2.txt<\/span>
\n a3.txt<\/span>
\n a4.txt \u00a0<\/span><\/p>\n

Step 5 now we will check \u00a0then we will found we have alltxt.tar new file
\n [root@localhost ~]# ls -lh<\/strong><\/span>
\ntotal 320.MB<\/span><\/p>\n

-rw-r–r– 1 root root 39M Jan 12 07:27 a1.txt<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:27 a2.txt<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:27 a3.txt<\/span>
\n -rw-r–r– 1 root root 39M Jan 12 07:37 a4.txt<\/span>
\n-rw-r–r– 1 root root 153M Jan 12 07:46 alltxt.tar<\/span><\/p>\n

Step5 next we will remove all txt file .
\n[root@localhost ~]# rm -rf a1.txt a2.txt a3.txt a4.txt<\/strong><\/span><\/p>\n

Step 6 now if we want check we check alltxt.tar in which file include \u00a0so we can look through this commands
\n[root@localhost ~]# tar -tvf alltxt.tar<\/strong><\/span>
\n-rw-r–r– root\/root 40000000 2017-01-12 07:27:06 a1.txt<\/span>
\n -rw-r–r– root\/root 40000000 2017-01-12 07:27:17 a2.txt<\/span>
\n -rw-r–r– root\/root 40000000 2017-01-12 07:27:30 a3.txt<\/span>
\n -rw-r–r– root\/root 40000000 2017-01-12 07:37:41 a4.txt<\/span><\/p>\n

Step 7 now if we want decompress we can do this belong commands
\n[root@localhost ~]# tar -xvf alltxt.tar<\/strong><\/span>
\na1.txt<\/span>
\n a2.txt<\/span>
\n a3.txt<\/span>
\n a4.txt<\/span><\/p>\n

w.zip Compress<\/h1>\n

[root@localhost ~]# zip w.zip a1.txt a2.txt a3.txt a4.txt\u00a0<\/strong><\/span><\/p>\n

(note- we can also use for all txt file\u00a0[root@localhost ~]# zip w.zip .txt *)<\/strong><\/p>\n

adding: a1.txt (deflated 90%)<\/span>
\n adding: a2.txt (deflated 90%)<\/span>
\n adding: a3.txt (deflated 90%)<\/span>
\n adding: a4.txt (deflated 90%)<\/span><\/p>\n

 <\/p>\n

now here you can look my all txt file size is 160 mb but after compress only 16 mb file size
\n[root@localhost ~]# ls -lh<\/span><\/strong>
\ntotal 176.MB
\n-rw-r–r– 1 root root 39M Jan 12 07:27 a1.txt
\n-rw-r–r– 1 root root 39M Jan 12 07:27 a2.txt
\n-rw-r–r– 1 root root 39M Jan 12 07:27 a3.txt
\n-rw-r–r– 1 root root 39M Jan 12 07:37 a4.txt<\/span><\/strong><\/p>\n

-rw-r–r– 1 root root 16M Jan 12 08:55 w.zip<\/strong><\/span><\/p>\n

now we delete a1.a2.a3.a4 txt file and then decompress<\/p>\n

[root@localhost ~]# rm -rf a1.txt a2.txt a3.txt a4.txt\u00a0<\/strong><\/span><\/p>\n

Step 8 we can decompress through belong commands
\n[root@localhost ~]# unzip w.zip<\/strong><\/span>
\nArchive: w.zip<\/span>
\n inflating: a1.txt<\/span>
\n inflating: a2.txt<\/span>
\n inflating: a3.txt<\/span>
\n inflating: a4.txt<\/span><\/p>\n

GZIP\/GUNGIP(.gn) Compress<\/h1>\n

gunzip compression in we can compress one by one file we can say this compress only get one particular file
\n[root@localhost ~]# touch hello.txt<\/strong><\/span>
\n[root@localhost ~]# dd if=\/dev\/sda of=hello.txt bs=2M count=100<\/strong><\/span>
\n100+0 records in<\/span>
\n 100+0 records out<\/span>
\n 209715200 bytes (210 MB) copied, 2.96087 seconds, 70.8 MB\/s<\/span><\/p>\n

here i create hello.txt file its size is \u00a0210MB now i compress through gzip<\/p>\n

\u00a0<\/span>
\n [root@localhost ~]# gzip hello.txt<\/strong><\/span>
\n [root@localhost ~]# ls -lh<\/strong><\/span>
\n–rw-r–r– 1 root root 67M Jan 12 09:18 hello.txt.gz<\/span>
\nso you can look hello.txt file size is only 67mb<\/p>\n

fi we want uncompressed we can do it belong \u00a0commands
\n[root@localhost ~]# gunzip hello.txt .gz<\/span><\/strong><\/p>\n

we can look
\n[root@localhost ~]# ls -lh<\/strong><\/span>
\n-rw-r–r– 1 root root 200M Jan 12 09:18 hello.txt<\/span><\/p>\n

BZIP2\/BUNZIP2(.bz2)\u00a0compression\u00a0<\/strong><\/h1>\n

this compression is very powerful compression but its bad think it take time.\u00a0BZIP2\/BUNZIP2(.bz2) \u00a0 compression also particular file<\/p>\n

here i create 419 mb demo.txt file we will compress through BZIP2<\/p>\n

[root@localhost ~]# touch Demo.txt<\/span><\/strong>
\n [root@localhost ~]# dd if=\/dev\/sda of=Demo.txt bs=2M count=200<\/span><\/strong>
\n200+0 records in<\/span>
\n 200+0 records out<\/span>
\n 419430400 bytes (419 MB) copied, 14.6637 seconds, 28.6 MB\/s<\/span>
\nwe will do compress through belong commands
\n[root@localhost ~]# bzip2 Demo.txt<\/span><\/strong>
\nyou can look just Demo.txt file \u00a0after compression only 111Mb
\n-rw-r–r– 1 root root 111M Jan 12 09:37 Demo.txt.bz2<\/strong><\/span><\/p>\n

we can do decompress through this commands<\/p>\n

[root@localhost ~]# bunzip2 Demo.txt.bz2<\/strong><\/span><\/p>\n

TAR+GZIP(tar.gz \/ .tgz) compression\u00a0<\/strong><\/h1>\n

TAR+GZIP(tar.gz \/ .tgz)\u00a0<\/strong>this compression we can apply on group of file<\/p>\n

here i explane\u00a0in details<\/p>\n

here i create four demo file through touch commands
\n[root@localhost expirment]# touch demo.txt<\/strong><\/span>
\n [root@localhost expirment]# touch demo1.txt<\/strong><\/span>
\n [root@localhost expirment]# touch demo2.txt<\/strong><\/span>
\n [root@localhost expirment]# touch demo3.txt<\/strong><\/span>
\n [root@localhost expirment]# touch demo4.txt<\/strong><\/span><\/p>\n

you can look through this commands
\n [root@localhost expirment]# ls -lh<\/strong><\/span>
\ntotal 20K
\n-rw-r–r– 1 root root 0 Jan 12 10:17 demo1.txt<\/span>
\n -rw-r–r– 1 root root 0 Jan 12 10:17 demo2.txt<\/span>
\n -rw-r–r– 1 root root 0 Jan 12 10:17 demo3.txt<\/span>
\n -rw-r–r– 1 root root 0 Jan 12 10:17 demo4.txt<\/span>
\n -rw-r–r– 1 root root 0 Jan 12 10:16 demo.txt<\/span><\/p>\n

then here i provide every file 200Mb size
\n[root@localhost expirment]# dd if=\/dev\/sda of=demo.txt bs=2M count=100<\/span><\/strong>
\n100+0 records in<\/span>
\n 100+0 records out<\/span>
\n 209715200 bytes (210 MB) copied, 0.597468 seconds, 351 MB\/s<\/span>
\n[root@localhost expirment]# dd if=\/dev\/sda of=demo1.txt bs=2M count=100<\/strong><\/span>
\n100+0 records in<\/span>
\n 100+0 records out<\/span>
\n 209715200 bytes (210 MB) copied, 0.361243 seconds, 581 MB\/s<\/span>
\n[root@localhost expirment]# dd if=\/dev\/sda of=demo2.txt bs=2M count=100<\/strong><\/span>
\n100+0 records in<\/span>
\n 100+0 records out<\/span>
\n 209715200 bytes (210 MB) copied, 2.37261 seconds, 88.4 MB\/s<\/span>
\n[root@localhost expirment]# dd if=\/dev\/sda of=demo3.txt bs=2M count=100<\/strong><\/span>
\n100+0 records in<\/span>
\n 100+0 records out<\/span>
\n 209715200 bytes (210 MB) copied, 0.669441 seconds, 313 MB\/s<\/span>
\n[root@localhost expirment]# dd if=\/dev\/sda of=demo4.txt bs=2M count=100<\/strong><\/span>
\n100+0 records in<\/span>
\n 100+0 records out<\/span>
\n 209715200 bytes (210 MB) copied, 0.353607 seconds, 593 MB\/s<\/span><\/p>\n

here we will look every file size is 200MB
\n[root@localhost expirment]# ls -lh<\/strong><\/span>
\ntotal 1002M<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:18 demo1.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo2.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo3.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo4.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:18 demo.txt<\/span><\/p>\n

now we will compress through\u00a0TAR+GZIP(tar.gz \/ .tgz)\u00a0<\/strong>\u00a0compression<\/p>\n

[root@localhost expirment]# tar cvfz all.tgz *txt<\/strong><\/span>
\ndemo1.txt<\/span>
\n demo2.txt<\/span>
\n demo3.txt<\/span>
\n demo4.txt<\/span>
\n demo.txt<\/span><\/p>\n

now you can look 800MB file compress with 331MB
\nroot@localhost expirment]# ls -lh<\/strong><\/span>
\ntotal 1.4G<\/span>
\n -rw-r–r– 1 root root 331M Jan 12 10:33 all.tgz<\/span><\/strong>
\n -rw-r–r– 1 root root 200M Jan 12 10:18 demo1.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo2.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo3.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo4.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:18 demo.txt<\/span><\/p>\n

now we can delete all Demo.txt file<\/p>\n

\u00a0[root@localhost expirment]# rm -rf *txt<\/strong><\/span>
\n[root@localhost expirment]# ls -lh<\/span>
\ntotal 331M<\/span>
\n -rw-r–r– 1 root root 331M Jan 12 10:33 all.tgz<\/span><\/p>\n

[root@localhost expirment]# tar xvzf all.tgz<\/span><\/strong>
\ndemo1.txt<\/span>
\n demo2.txt<\/span>
\n demo3.txt<\/span>
\n demo4.txt<\/span>
\n demo.txt<\/span><\/p>\n

TAR+BZIP2(tar.bz2\/.bz2) Compression\u00a0<\/strong><\/h1>\n

this compression also use TAR help and compress group of file<\/p>\n

so let we start before i told you.You wil \u00a0create \u00a0any 5-6 .txt.\/mp3\/ .mp4 \u00a0file<\/p>\n

so now here i agree you have four .txt file then i compress my demo.txt file here<\/p>\n

\u00a0[root@localhost expirment]# tar cvfj all.tbz2 *.txt<\/strong><\/span>
\ndemo1.txt<\/span>
\n demo2.txt<\/span>
\n demo3.txt<\/span>
\n demo4.txt<\/span>
\n demo.txt<\/span>
\nthen we will look here tbz2 file size is 307MB
\n[root@localhost expirment]# ls -lh<\/strong><\/span>
\ntotal 1.7G<\/span>
\n -rw-r–r– 1 root root 307M Jan 12 10:52 all.tbz2<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:18 demo1.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo2.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo3.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:19 demo4.txt<\/span>
\n -rw-r–r– 1 root root 200M Jan 12 10:18 demo.txt<\/span>
\nthen we will delete all demo file through this commands<\/p>\n

[root@localhost expirment]# rm -rf *.txt<\/strong><\/span>
\nwe can decompress through this commands
\nroot@localhost expirment]# tar xvjf all.tbz2<\/strong><\/span>
\ndemo1.txt<\/span>
\n demo2.txt<\/span>
\n demo3.txt<\/span>
\n demo4.txt<\/span>
\n demo.txt<\/span><\/p>\n

if you will have any problems in compression please comments here i will solve your problem<\/p>\n

Thank you<\/p>\n
