> Run commands on multiple CPU cores.
Gzip several files at once, using all cores:
parallel gzip ::: {file1} {file2} {file3}
Read arguments from stdin, run 4 jobs at once:
ls *.txt | parallel -j4 gzip
Convert JPG images to PNG using replacement strings:
parallel convert {} {.}.png ::: *.jpg
Parallel xargs, cram as many args as possible onto one command:
{args} | parallel -X {command}
Break stdin into ~1M blocks, feed each block to stdin of new command:
cat {big_file.txt} | parallel --pipe --block 1M {command}
Run on multiple machines via SSH:
parallel -S {machine1},{machine2} {command} ::: {arg1} {arg2}
