The value of the variable EXP is specified between ", so the shell interprets the value before affectation.
$6 is replaced by the value of argument 6 which seems to be be not set in your case.
Protect $6 with \ to avoid substitution:
or use simple quotes ', in that case internals simple quotes must be protected :

Can someone please help me with this SHELL script?
I need to create a script that gets a positive number n as an argument. The script must calculate the factorial of its argument. In other words, it must calculate n!=1x2x3x...xn. Note that 0!=1.
Here is a start but I have no clue how to... (3 Replies)
I have a script which is taking a 10 character variable (BOC) input by the user. If it begins with a zero, the script unwittingly strips that off, & passes a 9 characters variable.
echo -n "Enter core-follow date/time for BOC: "
setenv BOC $<
The next bit of code picks up the 9... (4 Replies)

Hi,
We are in the process of migrating from AIX to Linux. There is a script of type "executable (RISC System/6000) or object module not stripped" on AIX and we are unable to read the contents of it.
Is there a way to read the contents of the file on AIX, so that we can rewrite the code in... (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.
