Removing text

Hi! Trying to remove the literal text "%st" from the command line return value: 0.0%st as in: [$] printf "0.0%st" | perl -pe 's/\%st//' I have also tried: [$] printf "0.0%st" | perl -pe 's/\Q%st\E//' Neither works. Would be happy if someone had any input here! :-) Thanks! Richard Taubo --

Re: Removing text

Hi Richard, When you printf "0.0%st” in the command line, it prints 0.0t And that is the string piped to perl. This is perhaps why you didn’t succeed. J -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.or

Hi, and thanks to Shawn H Corey, Jing Yu. I see that I have not been specific enough. (And sorry for the top posting). The full (bash) script with perl parts looks like this: [$] top_return=$(top -n1 | head -5) [$] io_return=$(printf "%s\n" "$top_return" | grep "^Cpu(s)") [$] io_all=$(printf "

Removing text to the end of the line.

Hi all, I have a bunch of C++ source files that contain the string PCN: sometext where somtext is an arbitary sequence of characters. Whenever the text "PCN:" occurs, I want to remove it and everything else to the end of the line. To do this, I have written the following script: while(<>) {

Re: Removing text to the end of the line.

Hi all, Once again - I figured it out... here is the updated script: while(<>) { my $current_line; $current_line = $_; $current_line =~ s/PCN:.*//g; print $current_line; } It worked after I took out the square brackets - although I am not sure why - since the square brackets *
