How to find string and delete before just in line?
Hello,

When my lines contain question mark, I use below command to delete the portion of the matching line coming after question mark:


Code:
sed 's/?.*//' SampleFile

SampleFile:
Code:
helloworldfirstline?mdksmyymsss
hellosecondlineworld?mdksmkkmsss
thirdhelloworld?mdksmccmsss


Output:
Code:
helloworldfirstline
hellosecondlineworld
thirdhelloworld

What if I wish to delete before the question mark in each line?

Expected output1:
Code:
mdksmyymsss
mdksmkkmsss
mdksmccmsss

or ...

Expected output2:
Code:
mdksmyymsss?
mdksmkkmsss?
mdksmccmsss?

With or without question mark, both are welcome.

Many Thanks
Boris

Code:

or
echo 'helloworldfirstline?mdksmyymsss' | sed 's/[^?]*//'
