Yahoo MX Records

Monday, April 26th, 2010

At long last, I’ve gotten yahoo to reveal two of their mx records. So the next time you have a client that is hooked on yahoo mail, just setup their server to use yahoo’s mail servers.

Thank you Yamu, from Yahoo!!

Sed find and replace in directory of files

Friday, April 9th, 2010

Today I needed to find and replace an error in 55,000 files, and decided to use grep and sed.
1) I created a sed source file with the following s/\$this/$this/g and saved it as s.sed (i’m removing the backslash in front of $this)
2) grep -rl ‘/$this’ /home/sandusky/pathtofiles/ | xargs sed -i -f s.sed

this second command looks for files in the path that contain the search term, then sed updates them for a single file you could just type it out, sed -i ‘s/find/replace/g’ < filename.ext (g for global replace all instances)
