Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Results

The Unix time command

man time is a good start - on Linux you get the GNU time version.

Note: some shells (e.g.,bash(1)) have a built-in time command that provides less functionality than the command described here. To access the real command, you may need to specify its pathname (something like /usr/bin/time).

GNU time

A call of /usr/bin/time gives a lot of information:

/usr/bin/time ls > /dev/null

	for f in "$@"
	do
	TMP=$(mktemp)
	SIZE_OLD=$(wc -c < "$f")
	echo "Optimizing '$f' of size $SIZE_OLD"

	Each existing unread and subsequent new emails after the script is started are
	passed as Mail objects to "process_email" function.Function header is provided
	but processing implementation is left to the user. Error logs are currently sent
	to a rotating log file (in the same directory as the script) and to STDOUT.
	Instead of polling or checking the server for new emails every now and then,
	IMAP IDLE check is utilized. Ensure that the IMAP server supports IDLE command
	and allows at least 5 minutes of idling*** and uses the default ports for this
	script to work. Tested to work with Gmail and default installations of MS
	Exchange Server.
