If you have a lot of .zip files that you want to extract, then use
xjobs like this:
$ ls -1 *.zip | xjobs unzip
If you want to do the same without getting the output of each unzip
task on your terminal, then try this:
$ ls -1 *.zip | xjobs -n unzip
To gzip all *.bak files in a given directory hierarchy, use it the fol‐
lowing way:
$ find . -name '*.bak' | xjobs gzip
To generate index files for a set of *.jar files, you can use the redi‐
rection feature of xjobs, and do the following:
$ ls -1 .jar | sed 's/(.)/\1 > \1.idx/' | xjobs jar tf
If you also want to capture the error output, than use >& instead of >.
