Below is a simple script that will find the path were the perl command reside.
=========================
Code:
#!/usr/bin/sh
nPerl=`which perl 2>>/dev/null|grep -v "no perl"`
if [ -z "${nPerl}" ]; then
echo "No Perl application exist..."
else
echo "Existing at $nPerl"
fi
=========================
When I execute this manually, it can find the correct path (/usr/contrib/bin/perl). But if I put it in cron, the value of nPerl is empty. The value returned by "which perl" is "no perl in /usr/bin /usr/sbin ."
Need your expert advise how I will resolve this problem. I haven't encounter any problem with Linux, AIX and Solaris when I execute this via cron.

Hi all,
I have a script that can be run via cron or via the command line.
Is there any way that I can place something on the script to be able to distinguish/differentiate whether the script was run via a user in the command line or whether it was run from the cron? (3 Replies)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
