#2bashumerate — iterate over files, lines, ranges, or lists with a consistent {} syntax. No for loops, no find -exec, no xargs flags to remember.
enumerate -f '*.sh' -- wc -l {}
enumerate -L a b c -- 'echo {}'
Under 150 lines of bash, pluable sources, NUL-safe.

Have you seen parallel?

#4 find -print0 | xargs -0 -I {} "the {} iterated command"Re: I wrote an bash enumerator because I was sick of xargs
#5find -print0 | xargs -0 -I {} "the {} iterated command"
And for most of those commands add a dash dash so that nothing with a dash prefix turns into options.

#7Not sure I see the point of this. Remembering a bunch of options on one tool is no better than a bunch of tools/constructs? Especially if the latter are useful elsewhere. And it can't be used for scripts unless you start shipping it alongside, which… nah.
Just go with
foo | while read X; do bar "$X"; doneRe: I wrote an bash enumerator because I was sick of xargs

#9On the topic of xargs replacements, I love gnu parallel.
The --dry-run flag of parallel made me confident to do more batch processing than I ever did with xargs.
Parallel has an option for almost everything, it's almost too much.
But I have shopped around for alternatives. The creator Ole Tange maintains a painstakingly long article of the alternatives and their differences. [0]
The gnu parallel book and reading materials [1] are excellent too.

#10find -print0 | xargs -0 -I {} "the {} iterated command"
Xargs is fine, but openbsd has a -J option and every time I read the man page to figure out how to use it I read the -I and -J options and my brain glazes over.
Other brain glazing obsd wierdness is it's two argument cd command, a cryptid I am unable to wrap my head around.
