I have a file as below:

mime PI Name: ISHO SUCCESS RATE RT, Value: 95.663826
scr PI Name: RRC Access Failures due to UU, Value: 0.13394141
prog PI Name: RRC Access Failures due to UU, Value: 0.16077702
sch PI Name: RRC Access Failures due to UU, Value: 0.11781933

I want to remove text PI till Value:. I tried

sed '/<PI>/,/</Value:>/d' 

Any help?

Replace everything from PI to Value: with empty string:

sed 's/PI.*Value://'

Using the d command in sed will delete the whole line. Also, I'm not sure why you're using < and >. Perhaps you're confusing them with < and > that grep uses to denote word boundaries? In that case, you should know that sed uses b for both types of word boundaries (beginning and ending). So you can write something like this:

sed -i 's/bPIb.*bValue:b//' your_file

For extra robustness, I would use perl for lazy quantification of . so that you only delete the text between the first occurrence of PI and the first occurrence of Value:. Of course it all depends on your use case.

perl -pi -e 's b PI b .*? b Value: bx' your_file

Use this below code to remove multiple lines between patterns (including lines with patterns):

sed "/PI/,/Value:/d" your_file

If you want to modify your_file directly:

sed -i "/PI/,/Value:/d" your_file
