Top Forums Shell Programming and Scripting How to write bash script for creating user on multiple Linux hosts? Post 302771444 by Chubler_XL on Wednesday 20th of February 2013 04:10:07 PM

It's horrible isn't it. The reason is that we need $UNIQUE to be expanded client side (before it's passwd over ssh) the double quotes are needed in the awk program so awk ends up seeing something like $3=="2213".

These double and triple levels of quoting is one of the main reasons I nearly always try and build my scripts client side, then scp them to the server and execute there. Anything longer than one or two lines turns into a quoting storm that's very difficult to read or debug.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
