• Logging of execution times
• Exclude certain commands, including parameter checking

Configuration

Configuration can be done by editing variables at the beginning of the script or by overwriting them through user config. The script will look for user config in:

~/.cmd-timer-conf

Possible options and their defaults:

# Where to install the script.
_CMDT_INSTALL_DEST="$HOME/.cmd-timer"

# Minimum time before starting the timer, in seconds.

_CMDT_EXCLUDE=( vi vim less emacs pv "tail -f" ssh telnet scp ftp man htop top 
    su screen irrsi irc "sudo -s" )

# Callback to execute after the timer finishes. It will be passed to eval.
_CMDT_CALLBACK='echo -ne \\007'

Script can automatically update itself from latest repository version.

Log format

Data is logged as a semicolon separated list, each entry in a new line.

timestamp ; timer ; command ; parameters

How does it work?

The timer is started by the DEBUG trap and stopped throught PROMPT_COMMAND.

Known issues

• Trap is not removed when uninstalling. It will disappear in your new session or you can remove it manually by running:

trap - DEBUG

• Problems with pipes!

TODO

• Better list of commands to exclude from timing
