Change the string in between " "
Hi All,

In I text file I had lot of columns as below and with different id's and I need to replace with only one "vreddy". Please let me know the command for it.

Code:
 CHANGE_USERID="bbhaska"
 CHANGE_USERID="skanaujeg"

vreddy
What is a 'vreddy'?

And what have you tried? This would appear to be a simple substitution problem.

A simple text editor might help.

Like so?
Code:
sed '/CHANGE_USERID/s/"[^"]*"/"vreddy"/' file

Output:
Code:
 CHANGE_USERID="vreddy"
 CHANGE_USERID="vreddy"
