GNU Parallel
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}}
