To keep the forums high quality for all users, please take the time to format your posts correctly.
First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)
Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.
Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Hi,
I'm getting a "bad number" error from the following conditional if statement. I understand the results of the grep command are not being treated a an integer but am unsure of the correct syntax. Any help would be appreciated.

I want to add a conditional statement to a user's .profile file. I have a certain number of users that log in and use the rksh (Restricted Korn Shell).

1) search for a file(say *.doc) from a path (say /home/user/temp)

initscript
INITSCRIPT(5) Linux System Administrator's Manual INITSCRIPT(5)NAME
initscript - script that executes inittab commands.
SYNOPSIS
/bin/sh /etc/initscript id runlevels action process
DESCRIPTION
When the shell script /etc/initscript is present, init will use it to execute the commands from inittab. This script can be used to set
things like ulimit and umask default values for every process.
EXAMPLES
This is a sample initscript, which might be installed on your system as /etc/initscript.sample.
#
# initscript Executed by init(8) for every program it
# wants to spawn like this:
#
# /bin/sh /etc/initscript <id> <level> <action> <process>
#
# Set umask to safe level, and enable core dumps.
umask 022
ulimit -c 2097151
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
# Increase the hard file descriptor limit for all processes
# to 8192. The soft limit is still 1024, but any unprivileged
# process can increase its soft limit up to the hard limit
# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
ulimit -Hn 8192
# Execute the program.
eval exec "$4"
NOTES
This script is not meant as startup script for daemons or somesuch. It has nothing to do with a rc.local style script. It's just a handler
for things executed from /etc/inittab. Experimenting with this can make your system un(re)bootable.
FILES
/etc/inittab, /etc/initscript.
