putting word in front of each line in a file

stryka · 12-06-2005, 12:37 PM

Hi, I have a list of suid programs in a file, and I am trying to figure out how I could go about echo'ing a specific phrase in front of every line in the file. More specifically, "chmod go-r"

Can someone assist me? Thanks

Code:

sed -e "s@^@chmod go-r@" -i file

or if you're used to /

Code:

sed -e "s/^/chmod go-r/" -i file

awk '{print "chmod go-r",$0}' <filename>

The text inside the quotes is literal. $0 represents an entire line. The comma puts a space between the literal text and the line.

Thank you both. It is my plans to learn sed and awk over christmas break. I appreciate your help
