Hi,

Maybe something like as :
Code:
awk -vArgz="$ArgZ" -vArgZB="$ArgZB" 'BEGIN{split(Argz,A,"\n")}
FNR == 1 {Line=0}
FNR == 1 && $0 ~ /^#!/ {Line=FNR}
$0 == A[2] || $0 == A[3]{next}
/^import/ {Line=FNR}
{B[FNR]=$0}
END{B[Line]=B[Line] Argz ArgZB;for (ll in B){print B[ll]}}' file

With your file example:
Code:
#!/usr/bin/env python2.7

import time
import re
import os.path
import os
import sys
MySpecialpath = os.path.abspath(sys.argv[0])
#
#REGEN
#REGEN
#REGEN

from bisect import bisect_left

This awk reads the file once and only once.


Regards.
