Ok, recenty I've been trying to automate tasks. It was recommended that I learn CSH. So off I go, and learn some simple CSH, but I don't get how to do the following task.
I'm trying to create a script, that creates a HTML file, say INDEX.HTML, for files listed on the command line. No linking or anything, just puts the names of the files on the command line inside the INDEX.HTML file.
I have no idea how to go about this, any pointers or examples?
csh is the most damaged of the shells available to you
Counterpoint
Also, CSH != C
In normal Bourne shell / bash / ksh, it would be this
Code:#!/bin/sh cat << HERE this is the head of the html file HERE for i; do echo $i done cat << HERE this is the tail of the html file HERE

Here's what I have so far
The problem I have now, is that I don't know how to 'scan' the argument list stored in argv. Ideally, I want the program to be runCode:#!/bin/csh -f set params = $argv[1-] set argc = $#argv set lsval = `ls` set title = "File Index" #defines head echo "<html>" echo "<head>" echo "<title>" echo "$title" echo "</title>" echo "</head>" echo "<body>" echo "<h1>" echo "$title" echo "</h1>" echo "<hr>" echo "<table>" #begin loop set var = `ls` foreach a($var) echo "<tr>" echo "<td>" echo "<pre>" echo " $a " echo "</pre>" echo "</td>" echo "</tr>" end #loop end #defines bodyend echo "</table>" echo "<hr>" echo "<address>" echo "Generated by $USER@`hostname` from $HOME" echo "</address>"
uprompt> ./htx2 *.html > index.html
So this means whatever the extension is , say *.c *.h, the script will find it in argv, and place it in var, so var = `ls *.html` say. Then only files with the html extension will be listed in the html file.
How can I do this. I've tried and cannot seem to get it. The users input, *.html, or *.c or whatever, can occur anywhere in the argv line. So it could follow other switches, whatever. How can I scan the line, and pass the search term to ls?

For the command line params, type
foreach a ($*)
