How do I unzip multiple / many files under Linux?
A. Linux or UNIX unzip command will list, test, or extract files from a ZIP archive, commonly found on MS-DOS systems.
When you want to unzip file using wild card, you have two options as follows.
Option # 1 : unzip multiple files using single quote (short version)
Type the command as follows:
$ unzip ‘*.zip’
Note that *.zip word is put in between two single quote, so that shell will not recognize it as a wild card character.
Option # 2 : unzip multiple files using shell for loop (long version)
You can also use for loop as follows:
$ for z in *.zip; do unzip $z; done

# If files are password protected, and we are not sure which password
for Z_FILE in *.zip; do
for PASSWD in [ pass123, PASS123, abc123, ABC123 ]; do
unzip -P $PASSWD $Z_FILE;
if [ $? = 0 ]; then # successful unzip
break
fi
done
done

Kamchybek,
This is an excellent hack.
Appreciate your post.

No probs, copyleft (c)
Actually I’ve seen yours:
$ for z in *.zip; do unzip $z; done
But, it was not enough for me, ’cause we have password protected ones… So, can say that idea comes from you
I just added a new feature (validation)…
I think it should/can be improved further to check for other exit status codes…
Maybe later some day…

I used to use for i in *.zip ; do unzip $i ; done as well but then I found out about the following command and use it all the time now.
unzip \*.zip
escape the asterik and you are good to go.

Hi
I tried unzip -P $PASSWD $Z_FILE; command but it is not working and for same zip file it is working in US with same password. I read in one of the web sites that, non USA system needs to install a patch for running above command. If yes Please let me know where can I get this patch else please let me know how to run this command.
Thanks
