[SOLVED] search through regex pattern in a file

Issue

I have a file with data in below format

abc {u_bit_top/connect_down/u_FDIO[6]/u_latch}
ghi {u_bit_top/seq_connect/p_REDEIO[9]/ff_latch
def {u_bit_top/connect_up/shift_reg[7]

I want to search for pattern *bit_top*FDIO* and *bit_top*REDEIO*in the file in each line and delete the complete line if pattern is found. I want output as

def {u_bit_top/connect_up/shift_reg[7]

I did using sed like sed "/bit_top/d;/FDIO/d;/REDEIO/d;" but this deletes the line having bit_top and FDIO and REDEIO separately. How I can search for above pattern and delete the line containing it. Shell or TCL anything will be useful.

Solution

You've been close! ;)

sed '/bit_top.*FDIO/d' input

Just input a regex to sed that matches what you want...
