General :: Bash : Pass Command Line Arguments Containing Special Characters?

Jul 14, 2010

I've written myself a linux program "program" that does something with a regular expression. I want to call the program in the bash shell and pass that regular expression as a command line argument to the program(there are also other command line arguments). A typical regular expression looks like "[abc]_[x|y]".Unfortunately the characters [, ], and | are special characters in bash. Thus, calling "program [abc]_[x|y] anotheragument" doesn't work. Is there a way to pass the expression by using some sort of escape characters or quotation marks etc.?

(Calling program "[abc]_[x|y] anotheragument" isn't working either, because it interprets the two arguments as one.)

General :: KDE - File Names With Special Characters ?

Feb 20, 2010

I am running gentoo openbox(rox file manager and desktop) I installed Digikam and Amarok. But I have problems with files which include special character in their names(such as �,�, �,ğ... ) The files are shown with strange and weird characters in the file dialogs of Digikam and Amarok.

I don't have this problem in other applications. I can create files with special character included. I think some settings do not agree with KDE4. How can I solve this problem? Does anyone have an idea? I also installed KDE systemsettings program but could not find a relevant config option for character encoding.

General :: Using Sed To Replace String With Special Characters In XML File?

Apr 29, 2011

I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:

OLD_STRING='<property name="webServiceHost">${jboss.bind.address}</property>'
NEW_STRING='<!--<property name="webServiceHost">${jboss.bind.address}</property>-->'

General :: Rsync On Windows To Make It Keep Special Characters In File-names

Sep 2, 2010

We're in the process of implementing an offsite backup of all our servers to a remote Linux server. We're using rsync over ssh.What I've found is that characters such as , , and are replaced on the Linux server with underscores.I don't mind if it changes these characters in the filenames of documents, but when it renames a language pack from Espaol.clx to Espa_ol.clx, it could cause issues for us further down the line.

What do I need to do differently to make the special characters copy over correctly? For the initial sync which will take place locally, before the machine is moved offsite, I have SAMBA enabled. I am able to copy files from Windows to the Samba share, retaining the original filename, though it looks different in the Linux directory listing, i.e. têst becomes stThese files get deleted by rsync when it runs, as it does not match the filenames.

Programming :: Bash-code To Rename Files Based On Config File

Apr 12, 2010

I'm writing a bash shell script that among various other things will traverse through a directory with hundreds of files and rename those who match a pattern found in a config file. It's expected that only about one in ten files will actually match, and those who don't, will simply just be ignored for this purpose.

This should for instance cause the file "dBase program file December 1987.prg" to be renamed "Clipper source code December 1987.prg", and conversely "C++ source August 1996.cpp" to be renamed "C source code August 1996.cpp" etc.A sample file such as "Random Data File.dat" should not be renamed here since it's not mentioned in the config file..What is the quickest, most elegant way to do this in bash?I am thinking of using bash's built-in regex matching combined with the /bin/rename utility, but don't quite know how to get started to catch this..I guess there are plenty ways of doing this in perl and elsewhere as well, but since this has to integrate into a pre-existing bash script, that's what I'm looking for.Anyone out there with a spare moment to offer a hint in the right direction?

Programming :: Bash Script Which Uses Awk To To Fetch A Line From A File?

Mar 24, 2010

Below is the part of my bash script which uses awk to to fetch a line from a file. Choice is set by a case, and i know it is receiving a proper number because of the echo statement. The problem is with the syntax of the awk command it says the error is with one of the ', but when I run the command at the command line and replace "$choice" with a number it works properly. So I am not sure what is going on.

echo "announcing choice $choice"
command="awk 'NR = "$choice"' beerpong.txt | say"

Programming :: In A Bash Script - Move A Line To A New File?

Apr 23, 2011

I've got a bash script I'm using to download a text file list of links via axel. What I'd like to do is automate the movement of completed links in the for loop when axel has successfully completed the download. This is what I've got. I can figure that I can just echo append the line to a new file, but what is the easiest way to delete the line with the link I just downloaded?

Code:

#!/bin/bash
for i in $( cat $1); do

Programming :: Changing A Line In A Config File While Installing The Program Using Bash Script

Jul 22, 2011

I am trying to write a bash script that installs a program fully automated for me. I am stuck at the one part where i need to change a line in one config file. I have tried various syntax for sed and none have worked. Maybe someone can suggest how to go about this. Since the line appears in the middle of the file, I can't use echo or cat. Also the file will be diffrent lengths depending on the install.

The line I need changed is:

I need that changed to:

the last syntax i tried is:

Yes this is for PNP4Nagios on centos 5.6 64bit. If i can get this figured out. I will be willing to post the whole thing for others to use. it will be used to install PNP after a working nagios install is done.

Programming :: Md5sum Bash Script With Escaped Characters?

Apr 15, 2010

I created a file holding all the md5 values of my files to find duplicates as follows: find /mnt -type f -print0 | xargs -0 md5sum >> ~/home.md5

I then tried to find duplicates and do ls -l on the result in such way: cat ~/home.md5 | awk '{print $1}' | sort | uniq -c | sort -nr | awk '{print $2}' | head -n 10 > ~/top10.md5

Now I attempted to do an ls -l on the files using the command: for i in `cat ~/top10.md5`;do grep $i ~/home.md5 | while read checksum path; do echo "`echo $(printf '%q' "${path}")`" | xargs ls -l; done; done

This works well on most files, however it does not work when filenames have special letters in them that gets escaped such letters with accent etc. These become for examle 303.

Are there any ways I can use the escaped 303 strings with path names, or any better way I can do this?

Programming :: BASH Sort List By End Of Line To X Position In Each Line?

Aug 18, 2010

I'm trying to make another file annotation script a little speedier than it has been by the up-until-now proven method of checking the last four characters in a filename before the "dot" (eg .jpg, .psd) against a list of known IPTC categories and Exiv2 command files. It occurred to me that if one script generated a list of files in directory foo, and the same or another script sorted that list by that four-letter tag,then that list could be used(instead of a for/do/done loop on the real files in the folder) by the command-file-matching script to "vomit out" which annotator file would go with file nastynewfile.jpg, f'r'instance. The script I had been using for this task looks like this:

Code:

while read 'line';
do
sp=$(echo $line)
vc=$(echo $sp | cut -d"," -f1)
cv=$(echo $sp | cut -d"," -f2)

[code]....

Where I seem to be stuck is with how to sort the lines in templist, which may be any number of different lengths, from back to front. sort -k looked promising, except it seems only to work the other way round. I thought of invoking a

Code:

q=$(expr length $line); echo $q
n=$[q-8]; echo $n

kind of thing, but that presented the problems of how to sort by those, how to tell sort where to find them (grep?) and how to "stitch them back in" to the original list, which is what I want to sort in the first place.
