the entire token - "abc" and replaces with "X" ?

yields -
X123 abc

IPESCRIPT(1) General Commands Manual IPESCRIPT(1)
NAME
ipescript - Run an Ipe script (written in Lua)
SYNOPSIS
ipescript script { arguments }
DESCRIPTION
ipescript runs an Ipe script written in Lua. The Ipe bindings are automatically available in the script. Ipescript looks for the script
in any of the script directories.
The script argument should not contain the .lua extension.
ENVIRONMENT VARIABLES
ipescript respects the following environment variables:
IPELATEXDIR
the directory where ipetoipe runs Pdflatex.
IPESCRIPTS a list of directories where Ipescript will look for
scripts. When this variable is not set, Ipe searches first the current directory, then ~/.ipe/scripts, and finally the system-wide
Ipe script directory. When this variable is set, it should contain a list of directories, separated by semicolons. A single under-
score is replaced by the system-wide Ipe script directory.
IPEDEBUG
set this to 1 for debugging output from ipescript.
