Hi,
I was wondering if there was a way to append something to filenames based on a wildcard. For example, if I have the following files in a directory:
blah1
blah2
blah3
blah4
blah5
I want to rename these all to:
blah1.txt
blah2.txt
blah3.txt

Hi,
I've been searching for a quick way to do this with sed, but to no avail.
I have a file containing a long series of (windows) file paths that are separated by the pattern '@'. I would like to extract each file path so that I can later assign a variable to each path.
Here is the file:... (2 Replies)

I am looking at using grep to locate the line in the text file and them use awk to select a word or words out of it.
I know awk needs -v to allow a variable to be used, but also needs -F to allow the break up of the sentence and allow the location of separate variables.

kill
KILL(1) BSD General Commands Manual KILL(1)NAME
kill -- terminate or signal a process
SYNOPSIS
kill [-s signal_name] pid ...
kill -l [exit_status]
kill -signal_name pid ...
kill -signal_number pid ...
DESCRIPTION
The kill utility sends a signal to the processes specified by the pid operands.
Only the super-user may send signals to other users' processes.
The options are as follows:
-s signal_name
A symbolic signal name specifying the signal to be sent instead of the default TERM.
-l [exit_status]
If no operand is given, list the signal names; otherwise, write the signal name corresponding to exit_status.
-signal_name
A symbolic signal name specifying the signal to be sent instead of the default TERM.
-signal_number
A non-negative decimal integer, specifying the signal to be sent instead of the default TERM.
The following PIDs have special meanings:
-1 If superuser, broadcast the signal to all processes; otherwise broadcast to all processes belonging to the user.
Some of the more commonly used signals:
1 HUP (hang up)
2 INT (interrupt)
3 QUIT (quit)
6 ABRT (abort)
9 KILL (non-catchable, non-ignorable kill)
14 ALRM (alarm clock)
15 TERM (software termination signal)
Some shells may provide a builtin kill command which is similar or identical to this utility. Consult the builtin(1) manual page.
EXIT STATUS
The kill utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
Terminate the processes with PIDs 142 and 157:
kill 142 157
Send the hangup signal (SIGHUP) to the process with PID 507:
kill -s HUP 507
Terminate the process group with PGID 117:
kill -- -117
SEE ALSO builtin(1), csh(1), killall(1), ps(1), sh(1), kill(2), sigaction(2)STANDARDS
The kill utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
HISTORY
A kill command appeared in Version 3 AT&T UNIX.
BUGS
A replacement for the command ``kill 0'' for csh(1) users should be provided.
