Hi all,
I need a way to test from within a script if it is running from cron or from terminal.
The ways I found till now are:
1) test if $PPID corresponds to the cron daemon
2) see if $TERM has a valid terminal value or "'dumb", in which case it is ran by cron
... but I feel the... (2 Replies)
I am using tcsh
what could possibly be a problem, when using crontab to invoke a shell script. ?
The script has the read, write and execute permission to all users. And the script works as expected while executing it in stand-alone mode.
Is there a way to trace (like log) what error... (9 Replies)

I have a program R installed on Ubuntu under /usr/bin/R. I also have a different version installed under /home/user/R. I would like to invoke the locally installed program temporarily. How can I do this automatically by running a script and then switching to the default program?
thanks,

Hello All,
I have a text file containing output from a command that contains lots of escape/control characters that when viewed using vi or view, looks like jibberish. But when viewed using the cat command the output is formatted properly.
Is there any way to take the output from the cat... (7 Replies)

kill
KILL(1) Linux Programmer's Manual KILL(1)NAME
kill - terminate a process
SYNOPSIS
kill [ -s signal | -p ] [ -a ] [ -- ] pid ...
kill -l [ signal ]
DESCRIPTION
The command kill sends the specified signal to the specified process or process group. If no signal is specified, the TERM signal is sent.
The TERM signal will kill processes which do not catch this signal. For other processes, it may be necessary to use the KILL (9) signal,
since this signal cannot be caught.
Most modern shells have a builtin kill function, with a usage rather similar to that of the command described here. The `-a' and `-p'
options, and the possibility to specify pids by command name is a local extension.
OPTIONS
pid... Specify the list of processes that kill should signal. Each pid can be one of five things:
n where n is larger than 0. The process with pid n will be signaled.
0 All processes in the current process group are signaled.
-1 All processes with pid larger than 1 will be signaled.
-n where n is larger than 1. All processes in process group n are signaled. When an argument of the form `-n' is given, and it
is meant to denote a process group, either the signal must be specified first, or the argument must be preceded by a `--'
option, otherwise it will be taken as the signal to send.
commandname
All processes invoked using that name will be signaled.
-s signal
Specify the signal to send. The signal may be given as a signal name or number.
-l Print a list of signal names. These are found in /usr/include/linux/signal.h
-a Do not restrict the commandname-to-pid conversion to processes with the same uid as the present process.
-p Specify that kill should only print the process id (pid) of the named processes, and not send any signals.

Taken from BSD 4.4. The ability to translate process names to process ids was added by Salvatore Valente <svalente@mit.edu>.
