I have a pattern that I need to search in a BIG file.

This is the command I am using

Code:

awk '/EA2/ { print $0 }' filename

The error message that I get is :

Code:

awk: 0602-561 There is not enough memory available now.
 The source line number is 1.

I am guessing the file is too big and that is hwy I get this particular message. I wanted to check if there were any other ways to go about getting this thing going. The file is a fixed width file and the pattern 'EA2' occurs at 94-96.

I think all the records are in single line without the newline character.You can try fold command and awk it.

Yes the file is a mainframe file so everything could be on one line. I tried this:

Code:

fold -w 150 filename | awk '/EA2/ { print $0 }'>/home/test/EA2.dat

But the file EA2.dat comes out to be a 0 byte file. Also I wanted to maintain the format of the source file. Is there any way to do this?

Check whether EA2 is there in the input file with the same case.
To maintain the format use this

Code:

fold -w 150 filename | awk '/EA2/ { print $0 }'> tmp
tr -d '\n' tmp > /home/test/EA2.dat
