The check on the size of a file I perform in a tcsh script does not work. The size of my file is the following :
ls -l File.gpg
-rw-r--r-- 1 xuo users 3354637392 2011-05-07 15:31 File.gpg
The script is the following :
#!/bin/tcsh -f
set listOfEncryptFiles = `ls *.gpg`
foreach file ($listOfEncryptFiles)
set fileSize = `stat -c %s $file`
echo $fileSize

I really like pushd and popd, but I don't like their long spellings, so I made aliases: 'x' runs pushd and 'xx' runs popd. That's not bad, but I wish I could improve them in the following way:
x => If followed by a path, 'pushd' (and cd to) that path. If not given any arguments, run 'popd'.
xx => 'cd -'
The problem is implementing that pushd/popd in one command trick. Since tcsh does not have functions, I've been struggling hard to come with a solution. I made a script, and it works, but it only works within the context of the script. The script exits and not only am I still sitting in the same directory, but also my dirstack is emptied.
A similar problem: make 'cdd'. I remember using that program in DOS a long time ago. I would run 'cdd /path/to/directory' and cd to that path if it existed, or create it and cd to it if it didn't exist. Again, I made a script, but that only works within the context of the script, not my current shell. So the new dir is created, but my shell won't cd into it.
I want to write script at "tcsh" that send message to user ($DISPLAY) and let him to answer me.below command line that open xterm at any user displayQuote:setenv LESS "P'HIT q TO QUIT'"/usr/bin/xterm -display $USER_DISPLAY -geometry 60x7 +sb -rv -e less ./MESSAGE_FILEpressing "q" will close the window.there is any way to press "r" ->

View 1 Replies View RelatedOne day, I was altering the size of the icons to make them smaller. I first made them larger (to 150%), and then shrunk them down to 66%. I did this through Nautilus while being in the /var/www folder. The Desktop icons resized down to the 66%, as well as all other icons. However, the icons in the /var/www folder remained large (at the 150%). I've tried changing it, and no change occurs in the particular folder.

View 4 Replies View RelatedI tried to start a tcsh on my Fedora 7 (default shell is bash)
[ss@ssvm ~]$ tcsh
[ss@ssvm ~]$ echo $SHELL
/bin/bash
As you see, another bash shell started.
I looked at the tcsh file:
[ss@ssvm ~]$ ll /bin/tcsh
-rwxr-xr-x 1 root root 345348 2007-02-26 23:58 /bin/tcsh
[ss@ssvm ~]$ ll /bin/csh
lrwxrwxrwx 1 root root 4 2010-03-07 13:13 /bin/csh -> tcsh
It is not a link (but csh is). I don't understand why this is happening.
I'm so lost it's difficult to even pose my question. My default shell is bash; and I'd like [actually, required to] have the ability to type csh and enter the TC shell...but it's not working at all. All the changes I made to the ~/.bashrc file work great, but I can't seem to access tcsh to see if the commands in my ~/.tcshrc file work.
When I type "csh", my old PS1 [prompt] displays and I have to type "exit" to get back to the one in the bashrc file and then type "bye" to log out off the system.
I've spent the last 3 days researching this, but every article/blog/site discusses permanently changing my log in...NOT going to happen.
I am curious if perhaps I am doing something wrong extracting pages from a pdf doc using pdftk and creating a new file. I am only extracting the odd pages from the file and outputting them to a new file that is now only 20 pages instead of the input's 40 pages, yet the new output file is still 1.4Mb in size, the same as the original.
It seems strange to extract only half the pages of a large document and end up with a result that is the same size. how to streamline the resulting pdf's using pdftk?
BTW this is the command I am using, in case perhaps I am missing an option to optimize file size or something:
Code:
pdftk A=ch15.pdf cat A1-40odd output odd.pdf
I'm researching about symbolic links been used with samba / CIFS:I'd like that the user that uses a MS-Windows OS could see my shared folder on CentOS 5 and the symbolic links that are inside this folder. Well, it works but, the user will see that the size of the file is bigger than the real file. Apparently, CIFS gets the size of the symbolic link (aproxim.32K) and add it to the size of the file.Example 1: 100KB file, used with shared folder, MS-Windows's user will see 100KBExample 2: 100KB file, used with symbolic link inside a shared folder, MS-Windows's user will see 132KB. (Sym link + size of file)Is there a way to allow the user only see the size of the file, and not the file + symbolic links ?
View 1 Replies View RelatedI was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??
We have some large files with sampling data in it. Don't want to delete these files. But want to quickly overwrite the file with 0s and/or 1s and preserve the original file size.

I have been using tcsh for quite some time, both on a laptop running Ubuntu and a remote server running Slackware 11. No problem whatsoever. Now I am compiling and installing tcsh on a brand new Slackware 13 box and when I run tcsh I get this error:
Unknown colorls variable 'ca'
or
Unknown colorls variable 'hl'
I didn't have this problem in Slackware 11, why is it happening now?
So I tried the official Slackware package for tcsh. It works, but it's tcsh 6.15.00. Tcsh is at 6.17.00, which runs fine on my Slackware 11 box.
I investigated the problem on Google and all reports seem to refer to Fedora, some to Mandriva. Many of the threads, across several forums and sites, point to this LinuxQuestions thread:

I am using DD to backup entire system partitions and now I am trying to restore one. The resulting disk image from my buggy process has zero bytes. D'oh.It apparently thinks the image was trailing garbage and ignores it. It deletes the original file and replaces it with a zero byte .dd file. I have the original copy of the image in a dd.gz file. It's 6.3 GB so it may still contain the data.How do I get the original image back without destroying it again?

I just recently installed Ubuntu for our server, and I had a question about using tcsh. I'm trying to run a script of commands and the first line of my script is: Quote: #! /bin/tcsh -f I chmod +x my script, but when I type the name of my script at the command line i get this message: Quote: myscript: Command not found. the only way my script will work is if I type: Quote: tcsh myscript
Only then, will myscript execute its set of commands. I would like to be able to type the name of scripts without having to type tcsh at the beginning, each time. Is there a way to do that?
I'm trying to install a Brother MFC425CN printer on my Gentoo system. I have obtained the files needed from Brother and extracted the payload.
The script for creating the filter (endless echos) is a csh script, so I emerged tcsh and ran the script. No luck. CUPS does not see the filter, even though it is present and has the same owner, group, and permissions that work on my other gentoo system.
When I print a test page the log file says
Code:

Can't seem to use tcsh as my login shell under CentOS 5 as I used to (if I specify /bin/tcsh as my start-up shell, the windowing system doesn't come up), so am logging in under bash then switching to tcsh on top of that, but it won't allow display access from tcsh for my programs. Gives the "cannot connect to display" error that usually xhost + is the solution for, but xhost doesn't help in this case (won't even run under tcsh, says unable to open display "0.0"). $DISPLAY is set in .cshrc. Must be something simple, but can't seem to find a direction to head?
