Executing jobs in parallel using GNU parallel
Answer:
GNU parallel is a tool for executing jobs in parallel. It is not part of standard Linux distribution yet, so it is so worth to install it.
You can download the latest version from: http://ftp.gnu.org/gnu/parallel/
E.g.
# wget http://ftp.gnu.org/gnu/parallel/parallel-20101202.tar.bz2
# tar -jxvf parallel-20101202.tar.bz2
# cd parallel-20101202
# ./configure
# make && sudo make install
Example usages:
# echo -e "a\nb\nc" | parallel echo "foo"
foo a
foo b
foo c
