General :: Bash Script File Access Check?
Dec 10, 2010
I have been using linux for a bit of time but would still class myself as a noobie. I dont know excatly what I am looking for but I can best describe it in a sanario. I have started creating bash scripts which are looped indefinetly which checks afor files to process. my problem is, is there any way to check if the file is complete, as if the file is large and is being coppied from a different volume the file may still be copying or if the file is being uploaded by a user over samba/nfs, and if the file is still copying the process will most likely fail.

I have bash script for converting files. I have a problem. If file name is "corrupted" then mv command for that file will not work. For example file with "-" in front of the name.
Is there a way to check if in some folder (subfolder) all the files have correct file names or they don't?
If they are all correct -> OK proceed with execution of the script!
If they are not all correct -> NOT OK stop with execution of the script!

This script that I found online does the job it promises. it does convert the files to mp3 without an issue. What I need to include now is an if statement that says If $file.mp3 exists then delete $file.wav
Code:
#!/bin/sh
# name of this script: wav2mp3.sh
# wav to mp3
# Credit to the script creator (Nikesh Jauhari):
[Code]...
After that I'm stumped as to how to do the if statement

so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
unknown-hacker|544> count.sh 1 3
1
2
3
My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message

I know that $1 ... $n will set the argument to the values but what happened if I have many options in one scripts lets suppose.
I can run:
myscript -1stargument -2ndargument -3rdargument
or myscript -1stargument
or myscript -1stargument -3rdargument
In my scripts I have
if [ $1 = "-1stargument" -o $2 = "-2ndargument"] #for every instruction I need
fi
but is there any way to do:
if [ (any arguments or commands) = "(mydesired option ] ; then
(do this...)
fi

I have a bash script that messages the user periodically. Is there any way in the script to check if the screensaver is running, so the script doesn't spam messages while the user is away? The xscreensaver process is always running in the background, I've noticed.

I'm trying to write a script where I want to check if any of the parameters passed to a bash script match a string. The way I have it setup right now is if [ "$3" != "-disCopperBld" -a "$4" != "-disCopperBld" -a "$5" != "-disCopperBld" -a "$6" != "-disCopperBld"]but there might be a large number of parameters, so I was wondering if there is a better way to do this?EDIT:I tried this chunk of code out, and called the script with the option, -disableVenusBld, but it still prints out "Starting build". Am I doing something wrong?
while [ $# -ne 0 ]
do
arg="$1"

I have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.

I created some users on my Ubuntu 10.0.4 machine a long time ago (whilst experimenting). Some of these users can login to the system, and others were prevented from login in. I can't remeber which ones can login. I have the following questions:
How do I find out which users may login to the machine? How may I disable an existing user account from login in? How may I re-enable a previously (login) disabled user account so it an login again?

my partitioning layout was as follows
Vista Recovery
Windows 7
GRUB
Extended
-->Fedora 12 (ext4)
so, I shrunk my recovery in Windows 7 successfully, and booted into my Fedora 12 live cd to run Gparted, and move the partitions so that the free space could go towards fedora, I did such, and then I couldn't expand the partition to my dismay. Next, I woke up this morning, tried to boot to fedora to run SSH, grub loaded, but when I tried to boot fedora, I got the "File system check failed" error, and when I tried 7, it just went to a blank screen with a single "_" in the top left-hand corner.

I do a bit for for local charity that refurbishes and repairs computers, the proceeds going to 'steps' at Bolton. A donation of several sas hard drives has come in and I have got the job of wiping the data before re-sale. I have got a sata adapter and been using a live cd/dvd to access said drive but the nearest I've got is for the live disk (cfdisk) to recognise there is something there although it cannot read it. Any suggestions? Or do I need a special motherboard or O/S?

I am supposed to take some small files, and print them to a specific printer, such that the small files are concatenated into one file. The file name has to be included in the file that gets printed.
Should I be looking to concatenate the files into one file with the file names included, and then print them?
something like: -printfunction -printername < file*

I have a CentOS dedicated server running ProFTP. I have created user accounts which are meant for FTP access only but the users cannot connect to the FTP unless their shell access is /bin/bash
Here is an example line that is outputted when I use this command:
This user can access the FTP fine, but he can also access SSH which I don't want to allow him to do. If I set his shell access to /bin/false then he can't connect to the FTP.
What can I use in instead of /bin/bash to allow FTP but don't allow SSH?

I've got a script to recursively create symlinks in my home directory to my settings directory, to keep the files under version control. I would like it to skip files which are already symlinked via a parent directory. That is, if I have these files/directories:
~/foo/ -> ~/settings/foo/
~/settings/foo/
~/settings/foo/bar
, how do I check that ~/foo/bar and ~/settings/foo/bar are the same file?
Edit: D'oh, another few minutes of searching revealed the answer: readlink -f $path

I have a site that I login to to check updates. It does not have RSS because users need to authenticate themselves before getting access to the page. Is there a way to write a script that can login to the page and check whether the HTML has changed and then send me an email?

But when I compare the both .o files with diff command, it is resulting that two files are differing. How could/ what are commands we should use to understand the difference between two .o file's output.

Occasionally Ubuntu runs a file check, and I assume repair if necessary, at start-up. what do I type into Terminal if I want to run a file check without waiting for the automatic file check to start? The reason I ask is that my system wouldn't boot last week and after several attempts to reboot, the automatic file check came into play and corrected whatever was wrong. This process of rebooting my system several times before Ubuntu fixed itself was very time consuming and frustrating. I dare say that there is a command line to trigger this file check.

I checked the smbclient man but could not find any switch to us in combination with 'get' to check if the file has been modified before download.
