Shell 005: Redirect Part of a File

Suppose a file contains data starting from a given keyword (the content above the keyword is considered not relevant). If only the content from after the keyword is to be redirected to a new file (in a batch), this can be done using sed.

for i in file-*.log
sed -n '0,/DONE/!p' $i > ${i/file/new}

"!" tells it to ignore everything from the start of the file "0" to the first line containing the keyword "/DONE/", then p makes it print the rest, with a shell redirection of the output to a new file.
Regards to David the H. at LinuxQuestions for pointing this out to me.
