So I am new to unix, and actually anything outside drag and drop with the mouse (been learning for about a week so far) . I have been using the foreach command in tcsh because I am working on a group of files. Basically what I need is to insert part of the filename as the first line in the file. Here is what I have:
I also tried with double quotes - print($ENV{"i"}), but both only insert a blank space in the beginning of the file.
I tried in bash as well:
Again, only a blank space at the beginning of the file...
I have read some things about how it is difficult to export variables between languages (e.g. into perl), but I found one reference using $ENV with a variable from bash into perl. Is it possible to export the foreach or for variable into perl as in the command above?
Your forum has been mighty helpful over the past 3 days (I have learned tons because of it) so a big thank you to everyone that posts here!
Cheers

I want to search line-by-line for a string in a file, and I want to do this to a series of files in a directory. I'm doing this in tcsh
This works fine to do the search:

First, the "ln" command doesnt seem to work properly.
I have a file "target" that is pointing to "file1". I cannot access file1 but that shouldnt matter.
when I do this, ln -sf file2 target
I get permission denied that I cannot access the... (1 Reply)
Greetings!
I love the power and control offered by BASH but detest its syntax! Is there some alternative *nix shell language? (other than TCSH)
Or maybe a wrapper that affords the use of BASH commands via an easier syntax?

Hi All,
I'm trying to write a simple if statement in TCSH and I honestly can't figure out what I'm doing wrong. I've played around with all sorts of permutations of syntax.

I want to extract data from a ASCII file that looks like the one provided here (see input.txt). For this purpose I used sed commands.

shells
shells(4) File Formats shells(4)NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
/bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh,
/usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.
Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
