Hello,

Here is the explaination. We are searching for string "Process request" then we are making it's 1st field to null and printing the rest of the fields. As your input doesn't have "Process request" in 1st 3 lines so it will not look for those and all other lines it will remove the String "GMDCOM.27936 " too.



Thanks,
R. Singh

Hi,

In the command :

Code:
awk '/Process Request/{$1="";print}' file

awk is searhing for pattern "Process Request". When RE matched then it initializing $1 (first column) with BLANK ("")

at last printing the value of $0 (ROW).

Thanks

YB Smilie
