Question

Thanks everyone! I have another question.

I have a text file file1 below:

Code:
$ more file1
Group#=G1
 Role=a1 Role#=[001]
 User=Adam
 User=Ben
 Role=b1 Role#=[002]
 User=Carl
Group#=G2
 Role=a1 Role#=[001]
 User=Ben
 Role=c1 Role#=[003]
 User=Carl
Group#=G3
 Role=c1 Role#=[003]
 User=Adam

...and I want to create a Korn shell that would create the desired output below (Group,Role,User) when I ran the shell using the input file1:

Code:
G1,a1,Adam
G1,a1,Ben
G1,b1,Carl
G2,a1,Ben
G2,c1,Carl
G3,c1,Adam


I first thought of making it one group per line using the awk command below :

Code:
$ awk '{ if ( $0 ~ /Group/ && NR > 1 ) { printf "\n"; } printf $0; } END { printf "\n"; }' file1

Group#=G1  Role=a1 Role#=[001]  User=Adam  User=Ben  Role=b1 Role#=[002]  User=Carl
Group#=G2  Role=a1 Role#=[001]  User=Ben  Role=c1 Role#=[003]  User=Carl
Group#=G3  Role=c1 Role#=[003]  User=Adam

I not sure what to do after thisSmilie



Any help will be appreciated.

NAME
shtool-subst - GNU shtool sed(1) substitution operations SYNOPSIS
shtool subst [-v|--verbose] [-t|--trace] [-n|--nop] [-w|--warning] [-q|--quiet] [-s|--stealth] [-i|--interactive] [-b|--backup ext] [-e|--exec cmd] [-f|--file cmd-file] [file] [file ...] DESCRIPTION
This command applies one or more sed(1) substitution operations to stdin or any number of files. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -n, --nop No operation mode. Actual execution of the essential shell commands which would be executed is suppressed. -w, --warning Show warning on substitution operation resulting in no content change on every file. The default is to show a warning on substitution operations resulted in no content change on all files. -q, --quiet Suppress warning on substitution operation resulting in no content change. -s, --stealth Stealth operation. Preserve timestamp on file. -i, --interactive Enter interactive mode where the user has to approve each operation. -b, --backup ext Preserve backup of original file using file name extension ext. Default is to overwrite the original file. -e, --exec cmd Specify sed(1) command directly. -f, --file cmd-file Read sed(1) command from file. EXAMPLE
# shell script shtool subst -i -e 's;(c) ([0-9]*)-2000;(c) 1-2001;' *.[ch] # RPM spec-file %install shtool subst -v -n -e 's;^(prefix=).*;1 $RPM_BUILD_ROOT%{_prefix};g' -e 's;^(sysconfdir=).*;1 $RPM_BUILD_ROOT%{_prefix}/etc;g' `find . -name Makefile -print` make install HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications. SEE ALSO
