Millisecond resolution tic / toc timer pair utility for linux terminal. Supports id-based tic/toc pairs.
#!/bin/bash
function showHelp {
version=0.0.1
versionDate="2014-07-07"
echo "$0 - tic/toc timer pair
Usage: $0 [id] Stores initial time (w/optional id marker)
$0 [-u|--unique] Creates and returns unique id
Using optional ID is recommended, as it allows simulatenous usage.
Notes:
ttoc [id] (displays delta time since ttic was called)
Temporary timer file is stored at /tmp/.ttic.[ID.]time
Example
# Global timer (not recommended)
ttic && (do work) && ttoc
# Using FooBar as id
ttic FooBar && (do work) && ttoc FooBar
# Using a randomly generated id
id=\$(ttic -u) && (do work) && ttoc \$id
