Question

I have a jar file, i need to execute the files in it in Linux.
So I need to get the result of the unzip -l command line by line.
I have managed to extract the files names with this command :

unzip -l package.jar | awk '{print $NF}' | grep com/tests/[A-Za-Z] | cut -d "/" -f3 ;

But i can’t figure out how to obtain the file names one after another to execute them.
How can i do it please ?

Thanks a lot.

Here is my attempt, which also take into account Daddou’s request to remove the .class extension:

unzip -l package.jar | \
awk -F'/' '/com\/tests\/[A-Za-z]/ {sub(/\.class/, "", $NF); print $NF}' | \
while read baseName
do
    echo "  $baseName"
done

Notes:

• The awk command also handles the tasks of grep and cut
• The awk command also handles the removal of the .class extension
• The result of the awk command is piped into the while read… command
• baseName represents the name of the class file, with the .class extension removed
• Now, you can do something with that $baseName
