I have thousands of .zip files in one folder, I want to extract those using command or script, each .zip file to it own folder. I wish to run the unzip process multiple times. How can i do that?

@Siraj this question is about multiple ZIP files at a time, not about ZIP files within ZIP files. – Chai T. Rex Feb 28 '17 at 0:57

This will do the trick, run this on terminal
for f in *.zip; do unzip $f -d ${f%.*}; done
Ok redefined answer taking into consideration the comment:
In one file named unzip.sh put this code:
#!/bin/bash
LEN=${#}
COUNT=0
PROCESSES=20
ITERATE=$(( LEN/PROCESSES ))
for ((i=0;i<=ITERATE;i++))
do
LOWER=$(( i*PROCESSES+1 ))
HIGHER=$(( (i+1)*PROCESSES ))
./aux.sh ${@:$LOWER:$HIGHER} &!
done
In one file named aux.sh put this code:
#!/bin/bash
for f in $@; do unzip $f -d ${f%.*}; done
Remember to set both files with executions permissions by typing in the terminal: chmod +x unzip.sh aux.sh
Now all you have to do is executing the script by typing in the terminal: ./unzip.sh *.zip

Thank you, but i wish to run the unzip process several times because there are thousands of .zip files. – yarone Feb 27 '17 at 17:51

You want to unzip some zips each time and running the script several times until you made it? If so, can the zips already unzipped be deleted? – Diogo Vilela Feb 27 '17 at 17:54

I want to extract zip files, in order to accomplish it in a short time i wish to run the unzip process itself several times (parallel), each zip to its own folder. – yarone Feb 27 '17 at 19:25

Ok i think I can do a little script for you to run if you're interest, I'll post as another answer – Diogo Vilela Feb 27 '17 at 22:14

Thank you @Diogo Vilela, will it extract each zip file in its own folder? – yarone Feb 28 '17 at 16:03

xargs with -P n can be used to run a program in parallel for multiple files. The following, for example, runs 8 instances of unzip in parallel.
cd directory-with-zip-files
find . -name '*.zip' -print0 | xargs -0 -n 1 -P 8 unzip

If the files inside the zip files are in their respective folders, an easier solution would be to type this in the opened terminal of the zip files' folder:
unzip "*.zip"
