Hello expert,
What I want is to determine whether the script is called from CRON or it is executed interactively?
I tried the following but no luck:
#!/bin/ksh
cronID=`pgrep -x cron`
GPID=`ps -ef -o ppid,pid | grep " $PPID$" | awk '{print $1}'`
if ; then

My n00b question:
I am trying to write a script that I can place on a flash drive and then move from computer to computer and install a file, which is bundled with the script. (ie the script is at /Volumes/FlashDrive/Folder/Script, the file is at /Volumes/FlashDrive/Folder/File)
So far I have... (1 Reply)
Hi everyone,
Is there a slick way to determine the FULL name of a script that is running?
The variable ${0} just gives the relative path name.
I guess I could just do the following:
FULL_SCRIPT_NAME=${PWD}${0}Although that's pretty simple is there another way that I am missing?

Hi all,
Using sh/csh, unfortunately shell scripts are not my strong suit.
Trying to write a script that gets called from a program for pre-processing.
The program passes individual components of a UNC (//server/path1/path2/filename).
Thus the unc path of: //server/path1/path2/filename, is... (7 Replies)

ipcs
IPCS(1) BSD General Commands Manual IPCS(1)NAME
ipcs -- report System V interprocess communication facilities status
SYNOPSIS
ipcs [-abcMmopQqSsTt]
DESCRIPTION
The ipcs utility provides information on System V interprocess communication (IPC) facilities on the system.
The options are as follows:
-a Show the maximum amount of information possible when displaying active semaphores, message queues, and shared memory segments. (This
is shorthand for specifying the -b, -c, -o, -p, and -t options.)
-b Show the maximum allowed sizes for active semaphores, message queues, and shared memory segments. The ``maximum allowed size'' is
the maximum number of bytes in a message on a message queue, the size of a shared memory segment, or the number of semaphores in a
set of semaphores.
-c Show the creator's name and group for active semaphores, message queues, and shared memory segments.
-M Display system information about shared memory.
-m Display information about active shared memory segments.
-o Show outstanding usage for active message queues, and shared memory segments. The ``outstanding usage'' is the number of messages in
a message queue, or the number of processes attached to a shared memory segment.
-p Show the process ID information for active semaphores, message queues, and shared memory segments. The ``process ID information'' is
the last process to send a message to or receive a message from a message queue, the process that created a semaphore, or the last
process to attach or detach a shared memory segment.
-Q Display system information about messages queues.
-q Display information about active message queues.
-S Display system information about semaphores.
-s Display information about active semaphores.
-T Display system information about shared memory, message queues and semaphores.
-t Show access times for active semaphores, message queues, and shared memory segments. The access times is the time of the last con-
trol operation on an IPC object, the last send or receive of a message, the last attach or detach of a shared memory segment, or the
last operation on a semaphore.
If none of the -M, -m, -Q, -q, -S, or -s options are specified, information about all active IPC facilities is listed.
RESTRICTIONS
System data structures may change while ipcs is running; the output of ipcs is not guaranteed to be consistent.
BUGS
This manual page is woefully incomplete, because it does not at all attempt to explain the information printed by ipcs.
