How to unzip files into a specific directory on your system.
Just type the unzip command like this: unzip [zipfile.zip] -d [directoryname]
homer@deep-thought ~/Downloads $ unzip gzdoom-bin-1-8-02.zip -d myfolder/ Archive: gzdoom-bin-1-8-02.zip inflating: myfolder/fmodex.dll inflating: myfolder/gzdoom.exe inflating: myfolder/brightmaps.pk3 inflating: myfolder/gzdoom.pk3 inflating: myfolder/lights.pk3 inflating: myfolder/licenses.zip |
Then if you look in the myfolder directory and you will find your files in the folder.
homer@deep-thought ~/Downloads $ ls myfolder/ total 4.7M drwxrwxr-x 2 homer homer 4.0K 20-08-13 04:57 pm . drwxr-xr-x 9 homer homer 12K 20-08-13 04:57 pm .. -rw-rw-r-- 1 homer homer 240K 11-05-12 01:15 pm brightmaps.pk3 -rw-rw-r-- 1 homer homer 367K 11-08-10 01:54 pm fmodex.dll -rw-rw-r-- 1 homer homer 3.4M 23-06-13 11:35 pm gzdoom.exe -rw-rw-r-- 1 homer homer 659K 23-06-13 11:10 am gzdoom.pk3 -rw-rw-r-- 1 homer homer 17K 28-02-09 10:59 pm licenses.zip -rw-rw-r-- 1 homer homer 17K 11-05-12 01:15 pm lights.pk3 |
Use the unzip -l [zipfile.zip] command to list the contents of a zipfile. This is a very useful technique.
homer@deep-thought ~/Downloads $ unzip -l gzdoom-bin-1-8-02.zip Archive: gzdoom-bin-1-8-02.zip Length Date Time Name --------- ---------- ----- ---- 375808 2010-08-11 13:54 fmodex.dll 3534848 2013-06-23 23:35 gzdoom.exe 245268 2012-05-11 13:15 brightmaps.pk3 674279 2013-06-23 11:10 gzdoom.pk3 17131 2012-05-11 13:15 lights.pk3 17172 2009-02-28 22:59 licenses.zip --------- ------- 4864506 6 files |
This is how to extract a single file from a zipfile to the hard drive.
homer@deep-thought ~/Downloads $ unzip -c gzdoom-bin-1-8-02.zip licenses.zip > licenses.zip |
You can also read a text file from within a zip file with this command. This is useful when you just want to read the information about the files.
homer@deep-thought ~/Downloads $ unzip -c holyhell.zip HolyHell.txt | less |
The zipinfo command will also list the contents of a zipfile for you.
homer@deep-thought ~/Downloads $ zipinfo gzdoom-bin-1-8-02.zip Archive: gzdoom-bin-1-8-02.zip Zip file size: 2899539 bytes, number of entries: 6 -rw-a-- 2.0 fat 375808 b- defX 10-Aug-11 13:54 fmodex.dll -rwxa-- 2.0 fat 3534848 b- defX 13-Jun-23 23:35 gzdoom.exe -rw-a-- 2.0 fat 245268 b- defX 12-May-11 13:15 brightmaps.pk3 -rw-a-- 2.0 fat 674279 b- defX 13-Jun-23 11:10 gzdoom.pk3 -rw-a-- 2.0 fat 17131 b- defX 12-May-11 13:15 lights.pk3 -rw-a-- 2.0 fat 17172 b- defX 09-Feb-28 22:59 licenses.zip 6 files, 4864506 bytes uncompressed, 2898929 bytes compressed: 40.4% |
How to grep the contents of a zipfile. This is very easy when you use the zipgrep command.
homer@deep-thought ~/Downloads $ zipgrep "Doom II" cchest4.zip cchest4.txt: from "Doom II: Hell on Earth" (PC) cchest4.txt: from "Doom II: Hell on Earth" (PC) cchest4.txt: from "Doom II: Hell on Earth" (PC) cchest4.txt: from "Doom II: Hell on Earth" (PC) cchest4.txt: from "Doom II: Hell on Earth" (PC) cchest4.wad:Binary file (standard input) matches |
How to encrypt a zipfile and require a password to open it. Use the zipcloack command for this; you just give it a zipfile as a file argument and it will prompt you for a password to give the file and then it will be encrypted.
homer@deep-thought ~/Downloads $ zipcloak gzdoom-bin-1-8-02.zip Enter password: Verify password: encrypting: fmodex.dll encrypting: gzdoom.exe encrypting: brightmaps.pk3 encrypting: gzdoom.pk3 encrypting: lights.pk3 encrypting: licenses.zip |
If you want to unzip the encrypted file; just use the unzip command as usual.
homer@deep-thought ~/Downloads $ unzip gzdoom-bin-1-8-02.zip Archive: gzdoom-bin-1-8-02.zip [gzdoom-bin-1-8-02.zip] fmodex.dll password: inflating: fmodex.dll inflating: gzdoom.exe inflating: brightmaps.pk3 inflating: gzdoom.pk3 inflating: lights.pk3 replace licenses.zip?
