Pattern matching using awk
Hi I am trying to find a pattern match with column one containing 3 numbers.

input file tmp.lst

Code:
abcd456|1|23123|123123|23423
kumadff|a|dadfadf|adfd|adfadfadf
xxxd999|d|adfdfs|adfadf|adfdasfadf
admin|a|dafdf|adfadfa|||

output file tmp4.lst
Code:
abcd456|1|23123|123123|23423
xxxd999|d|adfdfs|adfadf|adfdasfadf


My code is

Code:
echo `awk '{if ($1 ~ /^[a-z]*[0-9][0-9][0-9]/) print NR, $0, "\n"} "\n"' tmp.lst` > tmp4.lst


the problem is i am getting all the output in same line like
Code:
abcd456|1|23123|123123|23423xxxd999|d|adfdfs|adfadf|adfdasfadf

Pls tune this to get a correct output.

Please use the code tags as required per forum rules.

You were close with your awk script, try removing the last instance of new line ("\n"), so it becomes:

Code:
echo `awk '{if ($1 ~ /^[a-z]*[0-9][0-9][0-9]/) print NR, $0, "\n"}' tmp.lst` > tmp4.lst

For me this outputs:

Code:
1 abcd456|1|23123|123123|23423

3 xxxd999|d|adfdfs|adfadf|adfdasfadf

Or, you could simply use:

Code:
awk -F"|" '$1~/[0-9][0-9][0-9]/' tmp.lst` > tmp4.lst

Why echo ` `?
Code:
awk '{if ($1 ~ /^[a-z]*[0-9][0-9][0-9]/) print NR, $0}' tmp.lst > tmp4.lst

Hello vamsekumar,

According to your condition the first field which has 3 digits following may also help.

Code:
awk  '($1 ~ /[0-9][0-9][0-9]/) {print NR OFS $0}' Input_file > Output_file

Thanks,
R. Singh
