The basic requirement
Hi Perderabo,
Thanks . You r right. That way the above command works fine.
But the problem is if I have more than one file in the input dir with the same name and with a different time stamp,
If we run this command it removes the date part of the file and places in that dir(this is for file f1)
For the second file f2, it repeats the same process and replaces the first file f1 as the file names are same without a time stamp.
The basic requirement is: Getting the file from a specific location and adding a column at the end of each line and placing the file back to the original dir.
I am using the sed command for adding a column at the end of each line.
export file=/var/opt/test/flat_file_extract.dtd
sed 's/^\(.*\)$/&\|N/' $file > file_temp
mv "file_temp" "$file
I dont knw how to incorporate the date dynamically for the sed command.
actual file name is flat_file_extract.20060127.dtd
The date stamp changes everday day and some times there may be more than 1 file with same name prefix with a different time stamp.At that time when I look for the process it should get the oldest file first and then other.
Can anybody help me out of this situation please?

Ok, so I have bunch of files that are named "orange__file_name.asm" and I want to batch rename them to "file_name.asm" I know that using "ls | sed s/orange__//" will get rid of the part of the file name I do not want. But how do I combine that with the mv command to actually do it?
Thanks

NAME
pcap_set_tstamp_type - set the time stamp type to be used by a capture device
SYNOPSIS
#include <pcap/pcap.h>
int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);
DESCRIPTION
pcap_set_tstamp_type() sets the the type of time stamp desired for packets captured on the pcap descriptor to the type specified by
tstamp_type. It must be called on a pcap descriptor created by pcap_create() that has not yet been activated by pcap_activate().
pcap_list_tstamp_types() will give a list of the time stamp types supported by a given capture device. See pcap-tstamp(7) for a list of
all the time stamp types.
RETURN VALUE
pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device, PCAP_WARN-
ING_TSTAMP_TYPE_NOTSUP on success if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called
on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't support setting the time
stamp type.
