How to set mutliple words variable from command line
I'm writing a script (C shell) to search for a pattern in file. For example scriptname pattern file1 file2 filenN
I use for loop to loop through arguments argv, and it does the job if all arguments are supplied. However if only one argument is supplied (in that case pattern ) it should ask to input file name or names, and then check for pattern. How I can set variable to include multiple words input from command line so I can use it in loop. Or even better is it possible to assign command line input to argv, so I don’t have to use the same loop twice only because it is different variable name (one to loop through argv if more than on argument, and second to loop through filenames variable if only one argument supplied). Below is the part of my script which is causing problem:
Any help will much appreciated.

I'm having an issue when I export within my program. I'm getting the variable name, not the variable value. I have a configuration file (config.txt) that has the values of the variables set as so:

This is probably the dumbest question you guys can get, but I'm trying, as a complete noob, to display the unix calendar for all the months without Saturday and Sunday showing. How can I remove those fields without having to type all the fields in individually such as:
cal -y | awk '{print $2,... (3 Replies)
within a unix window, how do you setup your session to extend a word, by hitting the "esc" key twice.
e.g.
ls -la scri (esc key, esc key)

cg
CG(1)CG(1)NAME
cg - Recursively grep for a pattern and store it.
SYNOPSIS
cg [ -l ] | [ [ -i ] pattern [ files ] ]
DESCRIPTION
cg does a search though text files (usually source code) recursively for a pattern, storing matches and displaying the output in a human-
readable fashion. It is intended to give some of the functionaly of AT&T's cscope(1) tool, with the advantages of simplicity and not being
language-specific. The script will colorize output if configured as such.
It is typically run with a Perl regular expression to search for. The search can be made case insensitive by using the -i option. A list
of files may also be specified with an additional argument after the pattern. Put the files pattern in quotes to make it be matched by
Perl rather than by the shell. Running the script with no arguments will recall the results of the previous search. After the search,
entries found can be edited using the vg(1) script. The -l option shows the last log made.
SOME EXAMPLES
cg - alone recalls the previous search results.
cg -i pattern - search the default list of files for all files matching the pattern (and case-insensitively).
cg pattern '*.c' - search recursively for pattern in all *.c files. This automatically converts '*' to '.*' and '.' to '.' for you and
does a Perl pattern match on all files in the tree.
cg pattern *.c - search through the shell-expanded list of *.c files, so not done recursively (in other words, only the files your shell
pass to the script as arguments).
cg -l - show the last log made.
COMMAND-LINE OPTIONS-i Do a case-insensitive search.
-l Show the last log made.
-p Toggle the default pager option. cg has a bulit-in pager function, which can be enabled or disabled by default (in .cgvgrc). If the
default is enabled, this option disables the pager; if the default is disabled, this option enables it.
-P Force the built-in pager to be disabled.
FILES
${HOME}/.cglast
Log file of the last search.
${HOME}/.cgvgrc
Per-user configuration file (if the defaults are not desireable).
${HOME}/.cgvg/*
Log files in $HOSTNAME.shell_pid form with the log of the last search.
