yexpand
YEXPAND(1) General Commands Manual YEXPAND(1) NAME
yexpand - tool to expand environment variables in Nypatchy cradles SYNOPSIS
yexpand inputfile [ outputfile ] DESCRIPTION
yexpand is a very simple script to expand environment variables in a text file to their current values in the shell environment. It was written to be used with nypatchy cradles. It is recommended you not try to use it for any other purposes (note BUGS below). USAGE
yexpand takes inputfile as input, replaces all instances of shell variables (in the form $VARIABLE or ${VARIABLE}) with their current val- ues in the environment, and saves the result to outputfile. Undefined variables are replaced with the empty string. If outputfile is not given, the result is instead saved to the current directory as a file of the same name as inputfile. Thus an input file in the current directory will be overwritten. BUGS
This script is very simple-minded. Since it basically just echos its input file as a here-doc, it will attempt to perform all types of shell substitution (command substitution, etc.) as well as variable substitution. Hence it is likely to fail on anything except the very simplest text files. Additionally, this script creates a temporary file. The file is created in the current directory, so there should not be security implica- tions. However, any existing file named file.yexp (where file is the basename of inputfile) in the current directory will be overwritten and then deleted. SEE ALSO
