Wednesday, March 25, 2009
Nice trick to pipe command line data through to convert it's alpha characters to upper or lower case. Most people dont even realize the 'tr' command exists on most linux/shell releases.
From UPPER to lower: tr [:upper:] [:lower:]From lower to UPPER: tr [:lower:] [:upper:]Example: ls /directory | tr [:lower:] [:upper:] | sort

Strip Leading Zeros In Shell
Thursday, December 04, 2008
Nice trick to strip leading zeros from an IP address at the command line.
(ie turn 002.203.017.001 to 2.203.17.1)
echo 002.203.017.001 | awk -F"." '{print int($1)"."int($2)"."int($3)"."int($4)}'

This blog is a place where I hope to put the snippets and trimmings of my geek'dom ... code samples that have served me well, tech links and other such things that'll I find useful. In short, any time I have to Google something, I tend to post it here for others to find as well.
Also, having owned 'digital-penguin.com' for many years and having worked with many a fellow geek, this site also serves as a place where I can always be found.
