- fix panic whan bash process never started (e.g. because of 'argument list too long')
- report time in log output
- compress temporary files with gzip (BestSpeed)
- default to bash instead of sh if it exists and SHELL is not specified
- output gargs version in help.
- restore --ordered (-o) to keep order of output same as input. this will cache 3*proccesses output waiting for the slowest job to finish. This means that if the user requested 10 processes (-p 10) then there could be up to 30 finished jobs waiting for a slow job to finish. If these are input memory, they are guaranteed to take <= 1MB (+ go's overhead). If they are larger than 1MB, then their data will be on disk. This is implemented carefully such that the performance penalty will be small unless there are few extremely long-running process outliers.
- set $PROCESS_I environment variable for each line (or batch of lines).
- read
GARGS_PROCESS_BUFFERto let user set size of data before a tempfile is used. - read
GARGS_WAIT_MULTIPLIERto determine how many finished processes will wait for single slow processes higher values improve concurrency at the expense of memory. - better cleanup of tmp files in case of process halt.
- Flush Stdout every 2 seconds.
- Nice String() output for *Command that show time to run, error, etc.
- Colorized errors
- Fix error/exit-code tracking when a tmpfile is used.
- remove --continue-on-error (-c) and make that the default. Introduce --stop-on-error (-s).
- add --log argument where each command is logged. If successful it is prefixed with '#' if not, it is printed as-is. If the entire execution ends succesfully, the last line will be '# SUCCESS' otherwise it will show, e.g. '# FAILED 3 commands'. The failed commands are easily grep'ed from the log with "grep -v ^# $log"
