View 8 Replies View RelatedI'm creating a bash script to check how much free space is left in /var directory then, if it hits a certain threshold, delete certain files with numbers for extensions (e.g. fileA.1, fileA.2 fileA.3, and fileA.4, fileB.1, fileB.2 fileB.3, and fileB.4 ). Here's a snippet from my script:

If I use a * as a wildcard for the number extension, the script fails. Maybe regex would work here, but I'm not particularly accomplished at it. Or some other construct.
I have been searching for 90 minutes for something that I "think" should be fairly easy. I'm pretty new to Bash Scripting so I could be completely wrong. Then again it may be a weird request to even need something like this. But here it is.I have a script written to convert data from one of our software version to another. The only thing I need to add to it is a "check to make sure the user running the script is in the /tmp directory".

I want to copy a file from an old directory to a new directory and ideally I would like that the 'mv' command itself could create the directory for me in one step...That is to say that the directory would not exist until 'mv' has been called as in:Code:mv olddirectory/file.dat newdirectory/file.datso mv would create the directory 'newdirectory' in the above call....I am not sure if this is possible however, that is to say I think it may be necessary that the directory 'newdirectory' already exists before I make the above call to mv, as when I make try the above call when 'newdirectory' doesn't exist I get the following error:Quote:mv: cannot move `test1/4215/4215-001R.fit' to `test2/test.fit': No such file or directoryso to sum up, my question is:is there some paramater for 'mv' that I can change so that it will create the new directory as well as copy the file and if not, are there other commands that might do this?
View 3 Replies View RelatedI downloaded a program called tonespace http://www.mucoder.net/en/tonespace/ which I extracted and then tried to execute the executable file with ./tonespace. This gives me the following message:
bash: ./tonespace: No such file or directory
When I use the command: file ./tonespace I get this: tonespace: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
I dont get it. The file is clearly there, yet when trying to execute it bash doesn't seem to recognize it.
It has permissions rwxr-xr-x and is not owned by root. Am I overlooking something?
I need to find if, in a folder any directories exist, except a certain one named "mes croquis".What I am trying to say, is that the re already is a directory named "my croquis", which I have to ignore.

IF anyDir EXIST AND name != "mes croquis"

I have a macro which I use with ROOT. In this macro I want to check if a part of string exist so I can ignore it inside a loop. So, inside a loop I want to have something like:
Code:
if (string == "pre_ti_data_bdt*" || string == "pre_ti_data_nn*")
continue;
but of course I cannot use * in this piece of code! How to do this trick in C++?
so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.

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 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 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 think as a result of a script that started duplicating files in a loop, the allotted capacity on my VPS filled up with multiple nested copies of the same files... After a reboot, I could delete most of them, but got rm stalled in certain directories...
after isolating which ones, I found this: a directory listing that lists the files, and at the same time tells me they are not there!!!
partial listing:
Code:
ls
ls: cannot access userkey.php: No such file or directory
ls: cannot access workshop.php: No such file or directory
ls: cannot access quiz.php: No such file or directory
ls: cannot access webservice_rest.php: No such file or directory

Have Apache running on Ubuntu Server. Say I have a domain, www.somewhere.com, and I have uploaded a file, phpinfo.php. If I hit http://www.somewhere.com/phpinfo.php, I get my file as expected. However, If I hit non-existent file http://www.somewhere.com/phpinfo/somefile.dat, it also acts as if I hit phpinfo.php, instead of giving me a 404 error. It seems that because the DIRECTORY "phpinfo" does not exist, it decided that I must have meant to hit phpinfo.php at the root of the site.
If I create an empty "phpinfo" directory then it behaves as expected and gives me a 404 not found page. This is reproducible for any other file name you can think of. I'm sure this is some Apache convenience behavior but I would like to disable it (it is messing with some mod_rewrite stuff I would like to do). Because it's hard to describe I cannot figure out which Apache option it might be (whatever I Google for gives me completely unrelated results).
