Replacing file text with sed-CodePudding

I'm doing a bash script and i have a txt file and i need edit some text inside it

I need to replace this

<h3> >> 1.10 Ping Desde XXXXXXXXXX01-PRD a 10.xxx.xx.xx ==> [ OK ] </h3>

to this

<h3> >> 1.10 Ping Desde XXXXXXXXXX01-PRD a 10.xxx.xx.xx ==> <span style="color: green">[ OK ] </span></h3>

I've trying with sed but with no success.

I've done this

sed -i 's/==> [ OK ]/==> <span style="color:green">[ OK ]</span>/g' "temp.txt"

with an error response

sed: -e expression #1, char 53: unknown option to `s'

then i tried a solution implemented for replacing urls, instead of "/" using "%"

sed -i 's%==> [ OK ]%==> <span style='color:green'>[ OK ]</span>%g' "temp.txt"

with no error message, but no file text change either.

If someone knows how to do it, i'll be grateful

You would need to escape the opening square brackets for your code to function

$ sed 's%==> \[ OK ]%==> <span style='color:green'>[ OK ]</span>%g' temp.txt

$ sed -E 's#([^[]*)(\[[^]]*])#\1 <span style="color: green">\2</span>#' temp.txt
<h3> >> 1.10 Ping Desde XXXXXXXXXX01-PRD a 10.xxx.xx.xx ==>  <span style="color: green">[ OK ]</span> </h3>

CodePudding user response：

You need to escape [] in the pattern.

$ echo "<h3> >> 1.10 Ping Desde XXXXXXXXXX01-PRD a 10.xxx.xx.xx ==> [ OK ] </h3>" | sed 's/==> \[ OK \]/==> <span style="color:green">[ OK ]<\/span>/g'
<h3> >> 1.10 Ping Desde XXXXXXXXXX01-PRD a 10.xxx.xx.xx ==> <span style="color:green">[ OK ]</span> </h3>
