        Stuart,

        this is easy:

                echo $PATH|sed -e 's/:/\^J/g' > pathtoedit
        
        will create file pathtoedit that contains each element in
        a separate line, edit it, and when you are done:

                 paste -s -d":" pathtoedit

        that's it. julius

Brett's:

        yes, awk could well do this
 
        echo $PATH | awk -F":" '{for (loop=1;loop <= NF;loop++) printf
$loop}'

Stuart,

Here's a Perl script I wrote some time ago. By default it breaks $PATH into
separate lines but you can specify any environmental variable (such as
MANPATH) as well:

- - - - - - - - - - snip - - - - - - - - - - #!/usr/bin/perl # # 05/00 wht;
v1.00: Created
#***************************************************************************
**
# showpath
#***************************************************************************
**
#
# PURPOSE
# shows the current path as separate line items
#
# SYNTAX
# showpath [ENV_VAR]
#
#***************************************************************************
**
#

$0 =~ s:^.*/::; # program name
$VERSION = "1.00"; # version

#---------------------------------------------------------------------------

--
# Main Routine
#
ShowPath: {
    if ( @ARGV ) { $VAR = $ARGV[0]; }
    else         { $VAR = "PATH";   }
    die "$0: \$$VAR not defined\n" unless ( $ENV{$VAR} );
    print "$VAR:\n";
    foreach ( split(/:/,$ENV{$VAR}) ) { print "  $_\n"; }
} #END ShowPath
- - - - - - - - - - snip - - - - - - - - - -

file pathtoedit that contains each element in a separate line, edit it, and
