Hi,
I am trying to find out patterns in file 1 using patterns stored in file 2. Following is the code
FILE1=inputfilename
FILE2=blacklist
blacklist
Code:
1203
97715555
20afEOF
Code:
egrep -f $FILE2 $FILE1
but the above code is not working either using egrep or grep. Just for your information file2 has more than 2000 different patterns with no blank line at the end & file1 has more than 100million records

Hi,
I'm trying to validate if a string matches a regular expression, but it is not working. Am I missing something? Do I need to scape any of the characters?
if echo 'en-GB' | egrep '({1,8})(-{1,8})*' >/dev/null; then
echo Valid value
