Programming :: Shell Scripting / Create A Shell Script Similar To Ls?
Jun 5, 2011I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then

General :: Create A Shell Script To Move Only Files Which Has Stopped Growing?
Jul 20, 2009An external service I dont manage pushes mediafiles into a shared directory on my server. I need to move these files into their correct directories automatically. The problem is that if I run my script as a cronjob once every 3 minutes, I notice that the script copies files which are still on their way into my server. So I need to figure out how to have the script check that the files are complete (done downloading) before the script moves the files. This is what I got so far:
Code:
#!/bin/sh
# Script by proximity 280709.
# Locate correct directory

General :: Backslash Preceding A Shell Command
Mar 21, 2011Reading a BASH script, I saw a find command preceded with a backslash. It was similar to this:
Code:
`find . -type f -name '*.xml' -print > xmlfilelist`
It's impossible to find documentation about this in man pages or on the internet, since 'backslash' are always evoked along with special characters. I also noticed that even though the command was surrounded with backquotes, the result was not affected to any variable. Maybe the backslash's presence is related with this?

General :: Clear Screen Command For BASH Shell
Jan 21, 2010I am unable to use clear or cls command on bash shell. I have recently installed Cygwin and am using that for practicing unix commands.
I see that I can use Ctrl + L to clear the screen. I created an alias in my .bashrc to do the same as
alias cls='^L'
This is how i defined other aliases e.g.
And they work. Hence I assume cls will work too but this is what I get when I try to give cls on command prompt. Am i missing something? Is there a way to do this?
Then someone suggested, You cannot alias keystrokes to commands or vice versa. You could just alias cls to an echo command: echo -en "x0c"
And I added the following to .bashrc,
Sourced the .bashrc file. No errors but cls still does not clear the screen. Infact when I typed the echo -en "x0c on command prompt as well, nothing happened. What does this command do?

General :: Shell Command To Find Newest File In Filesystem?
Apr 13, 2010I'm relatively experienced with UNIX and Linux, but this has me thrown for quite a loop, and it seemed like such a simple question. How would I go about finding the newest file in a file system? I thought something like:
Code:
ls -ltr `find /usr -type f`
would work, but I seem to be exceeding the argument maximum for ls:
ksh: 0403-029 There is not enough memory available now
I thought something involving xargs might work, but I really suck with that command.
