lipl is a command line tool that is similar to watch but has extended functions for commands outputing a number.
For example lipl 'ls' will show the output of ls and will refresh the result
every 1 second (by default).
Now if a command outputs a number like ls -1 | wc -l it will be able to plot
the result. In this case the plot will show a constant result until another
process adds or removes a file from the current folder. It can be useful when
downloading many files to the current folder and you want to follow the
progress. If you know that in total 1000 files will be downloaded, you can
simply add the option --target 1000 and a progress bar will be shown along
with an estimated time of completion.
brew tap yxdunc/tools
brew install lipl
A string containing a bash command.
If the bash command returns a number a plot will be shown (ex: ls -1 | wc -l)
If the bash command returns anything else the command shows the output and follow the same behaviour as watch
-n/--refresh-rate: the refresh rate in seconds
-t/--target: a target value that will be used to show a progress bar based on
the command outputs. A simple linear regression is used.
-l/--history-len: the number of results from the given command that are stored
and plotted.
--show-regression-line: when true shows the regression line used to compute
the ETA.
--show-target-line: when true shows an horizontal line representing the target
value.
