watch.py(1)¶

Name¶

watch.py - execute a program periodically, displaying the results

SYNOPSIS¶

wc.py [OPTIONS...] COMMAND

DESCRIPTION¶

watch.py runs COMMAND repeatedly, displaying its output and errors. This allows you to watch the program output change over time. By default, the program is run every two seconds. By default, watch.py will run until interrupted.

NOTE: This program differs significantly in execution from the GNU version of watch. This is because I have not been able to find a way to go fullscreen within a Windows command prompt. Instead, we clear the screen before displaying the new output (cls on Windows and clear on *nix). If you know of a way to achieve the desired results in a cross-platform way within Python, please open an issue in our issue tracker or better yet, open a pull request
