Conscript
Run a command and restart it on each new line of STDIN.
Usage
conscript command [args*]
Examples
Use like 'watch':
while true; do echo lol ; sleep 1; done | conscript ls
Which is equivalent to the xargs command:
while true; do echo lol ; sleep 1; done | xargs -L 1 -I % ls
Where Conscript differs from xargs is that if the script is a
long-running process, then subsequent incoming lines will kill that
process and restart it, rather than wait for it to finish.
Useful in conjunction with Commando:
commando -c echo | grep --line-buffered Add | conscript ls
Another example - Watch updates to a file:
commando | conscript bash -c "clear && less file.txt"
