Top Forums Shell Programming and Scripting appending data to last line of file Post 302431321 by Scrutinizer on Monday 21st of June 2010 01:36:29 PM

Something like this? Keeping the original date of the file:
Code:
[ "$1" != "" ] || exit 1
timestamp=$(ls -l "$1" | awk '{print $6,$7}' )
sed '$s|.*|& '"$timestamp ${1##*/}|" "$1" > "$1.$$" && touch -d "$timestamp" "$1.$$" && mv -f "$1.$$" "$1"

More precise with GNU versions:
Code:
[ "$1" != "" ] || exit 1
timestamp=$(ls -l --full-time "$1" | awk '{print $6,$7}' )
sed -i '$s|.*|& '"$timestamp ${1##*/}|" "$1" && touch -d "$timestamp" "$1"
