Remove last 2 portions of a string
I need to remove that last two parts of a string separated by an underscore

for example:
hello_g0f0_b6f5 Result should be hello
hello_come_here_g0f0_ffg0 Result should be hello_come_here
Hello_h_be_an_f_g1f1_ffe0 Result should be Hello_h_be_an_f
Ideal is we need to "cut" the last two parts of the string and print the rest
Code:
`echo $1|rev|cut -d"_" -f1-2 |rev`

This just prints the last 2 parts of the string.. I need the remaining part of the string..

Thanks!

Hi razor1979,

This it seems to work

Code:
$ echo "hello_come_here_g0f0_ffg0" | awk '{print gensub(/(.+)(_.+_.+)/, "\\1","g")}'
hello_come_here

Regards

what OS are you on?
Code:
echo 'Hello_h_be_an_f_g1f1_ffe0' | awk 'match($0,"_[^_][^_]*_[^_][^_]*$") {print substr($0,1, RSTART-1)}'
