I have a list of files in a directory that I want to check position 2-6 for a string of EPIP or EPCN. I ran the following command but it isn't working correctly:
ls EPDa*.*.*.data |cut -c1-30
All it is doing is cutting the file name not what is in the file. Any help would be appreciated. (3 Replies)

filebyproc.d
filebyproc.d(1m) USER COMMANDS filebyproc.d(1m)NAME
filebyproc.d - snoop opens by process name. Uses DTrace.
SYNOPSIS
filebyproc.d
DESCRIPTION
filebyproc.d is a DTrace OneLiner to print file pathnames as they are opened, including the name of the process calling the open. A line
will be printed regardless of whether the open is actually successful or not.
This is useful to learn which files applications are attempting to open, such as config files, database files, log files, etc.
Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
This prints new process name and pathnames until Ctrl-C is hit.
# filebyproc.d
FIELDS
CPU The CPU that recieved the event
ID A DTrace probe ID for the event
FUNCTION:NAME
The DTrace probe name for the event
remaining fields
The first is the name of the process, the second is the file pathname.
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
filebyproc.d will run forever until Ctrl-C is hit.
