Shell Programming and Scripting

I am trying to search a perticular pattern in all the files in a directory except one file.

i have used exclude grep to do that:

Code:

grep -c -E 'ñ|£' /interfaces/qi/archive/20130919/*.dat

is returning total 73 rows in the result
while

Code:

grep -c -E 'ñ|£' /interfaces/qi/archive/20130919/*[!MERCH_10.dat].dat

is not listing all the files except Merch_10 file. (35 files it listed)

Can you please help me on this.

Question:
If i am doing wrong in above command then how can i grep a pattern in a directory except one file (i dont want to chcek this pattern in one file).
I cannot specify all the files as there are 173 files present in directory.

Hi,

Please use code tags always for commands. Also kindly let us know the proper Output which you want to get.


Thanks,
R. Singh

Try this:

Code:

 find . \( -name "*.dat" -a ! -name MERCH_10.dat \) | xargs grep "string"

Here . ( dot ) is current directory for example.

Hi,

Thanks for your reply,
As i mentioned in folder there are 73 dat files but in result it is displaying only 35 files. rest of the files it is not checking. There is no unusual thing i noticed.

Hi,

Thanks for the code, is working as expected.
do you have any idea why the above mentioned command is not working as that one looks easier comapre to this.

grep has following options:

Code:

--exclude=GLOB ,
--exclude-from=FILE
--exclude-dir=DIR

Code:

grep 'string' --exclude=MERCH_10.dat *.dat

I am not sure your command can give expected result.

Hi,

Thanks for your help and correcting me as i was not applying the command in proper way. the command is working fine.
That is my concerns also as it is returing some results and skipping some. Dont know on what basis it is missing some files there is no pattern (as date/filename etc)

Neither do we, you have given no detailed information. Show exactly what you did, exactly what happened, and exactly what you expected to happen.
