Removing characters from end of $string
I am writing a script to search PCL output and append more PCL data to the end accordingly.

I need to remove the last 88 bytes from the string.
I have searched for a few hours now and am coming up with nothing. I can't use head or tail because the PCL output is all on one line. awk crashes on PCL and I cant match it in sed because the last bytes are not constant.

Are there any other shell commands for manipulating strings that would be appropriate for what I've described?

Thanks in advance for any help.
Craig

cjet

CJET(1) 						      General Commands Manual							   CJET(1)

NAME

       cjet - converts HP PCL to Canon CaPSL format

SYNOPSIS

       cjet [options]<input.pcl>output

DESCRIPTION

       This manual page documents briefly the cjet command.  This manual page was written for the Debian distribution because the original program
       does not have a manual page.

       cjet converts the common HP PCL page description language to Canon's CaPSL, which was used in the mid-1990s by some Canon  laser  printers.
       It is normally used as part of a printer filter script, like the Foomatic system.

OPTIONS

       -h     Show summary of options.

       -f     Use full paint mode instead of partial paint mode.  This requires the printer to have at least 1.5 MB of memory to work correctly.

       -p     Ignore paper size commands.  Useful for printing files formatted for paper size X on printers with paper size Y.

       -q     Quiet mode. Suppresses all warning messages.

       -x X   Shift  output on paper by X dots horizontally. Positive values of X shift to the right; negative values to the left.  Dots are 1/300
	      inch (0.085 mm).

       -y Y   Shift output on paper by Y dots vertically. Positive values of Y shift downwards; negative values shift upwards.

AUTHOR

       This manual page was written by Chris Lawrence <lawrencc@debian.org> based on the original README file by Michael Huijsmans for the  Debian
       project (but may be used by others).
