Shell Programming and Scripting

In bash (alas you didn't mention your system data) you could also use "extended pattern matching":

Code:

shopt -s extglob
grep -c -E 'ñ|£' /interfaces/qi/archive/20130919/!(MERCH_10*)

Thanks this command is now working as expected. but the problem is that now it checking for other files except MERCH_10, i need to check in All .dat files except MERCH_10.dat.

because if it checks for the all files then it can create problem if i placed some other extension having pound symbol my job will fail for unnecessary reason

Please find the difference in all command using exclude :[in this command Merch_10 file doesnot contains pound symbol, i want the 73 output using all the commands.]

Code:

grep -c -E 'ñ|£' /interfaces/qi/archive/20130919/*[!MERCH_10.dat].dat | wc -l
35
grep -c -E 'ñ|£' /interfaces/qi/archive/20130919/*.dat | wc -l 
73
grep -c -E 'ñ|£' /interfaces/qi/archive/20130919/!(MERCH_10*) | wc -l
151

I think that told clearly the difference in two commands. can you please tell me what extra information you need on this. My target is to achieve the count 73 when merch_10 file does have pound symbol.
