So i have this text:

2019/06/16 22:36:28 (UNIVERSE) * @{EE3F}Trytrytry sagt: @{F80F}going afk for a bit

I want to color the whole line in red for example. Then remove the unecessary parts to:

22:36:28 Trytrytry sagt: going afk for a bit

The removing of the parts is works already, but when i add:

norm="$(printf '\033[0m')"
boldred="$(printf '\033[0;1;31m')" 
sed -ue s/UNIVERSE/${boldred}&${norm}/g

It only colorize UNIVERSE and show it up, but i don't want let it show. I want to color the whole line where UNIVERSE was. So just adding color. So lets say:

IF (UNIVERSE) THEN color the line red in terminal, but let it be clean and don't show up the removed parts.

Any ideas?

  • The removing of the parts is works already please show what you mean by unnecessary parts and how you remove them. – simlev Jun 17 at 10:27

Change your sed line, for this one:

sed -ue 's/\(.*UNIVERSE.*\)/'${boldred}'\1'${norm}'/g'

with .*UNIVERSE.*, you are matching any whole line that contains UNIVERSE on it; then, you add the parentheses: \(.*UNIVERSE.*\) to capture the match (the whole line in this case), and then, you backreference your previous match with \1.

Well, you should:

  1. match lines containing your search string /UNIVERSE/
  2. remove the unnecessary parts
  3. replace beginning (^) with ${boldred}
  4. replace end ($) with ${norm}

Here's a tentative snippet that should show you the way, based on the posted specifications:

norm="$(printf '\033[0m')"; boldred="$(printf '\033[0;1;31m')"; sed -ure "/UNIVERSE/{s/^[^ ]* //;s/\(UNIVERSE[^}]+}//;s/sagt:[^}]+}/sagt: /;s/^/${boldred}/;s/$/${norm}/}" input1

Or, split for readability:

norm="$(printf '\033[0m')";
boldred="$(printf '\033[0;1;31m')";
sed -ure "/UNIVERSE/ {
    s/^[^ ]* //;
    s/\(UNIVERSE[^}]+}//;
    s/sagt:[^}]+}/sagt: /;
    s/^/${boldred}/;
    s/$/${norm}/
}"

I'm also providing a full, self-contained Perl solution:

perl -pe 'BEGIN{use Term::ANSIColor qw(:constants)} if(/UNIVERSE/){s/^\S*\s//;s/\(UNIVERSE[^}]+}//;s/sagt:[^}]+}/sagt: /;$_=RED.$_.RESET}'

Or, split for readability:

perl -pe 'BEGIN {use Term::ANSIColor qw(:constants)}
    if (/UNIVERSE/) {
        s/^\S*\s//;
        s/\(UNIVERSE[^}]+}//;
        s/sagt:[^}]+}/sagt: /;
        $_ = RED . $_ . RESET
    }'
0

The sed line in this snippet matches against UNIVERSE and then applies the red+bold attributes to the entire line. I've used tput to obtain the attribute values because it adapts depending on the terminal type (including where one isn't set, such as in a cron job):

# See "man 5 terminfo" for other portable settings
red=$(tput setaf 1 2>/dev/null)
bold=$(tput bold 2>/dev/null)
norm=$(tput sgr0 2>/dev/null)

# Perform the substitution
sed -e "/UNIVERSE/s/^.*$/${red}${bold}&${norm}/"
