When I run for i in $(find -name '*.ogg'); do echo '$i'; done I don't get one line per file as I expected. Instead, when a file name has a space in it, each word comes out in a separate line, so I can't run commands on the files.
View 4 RepliesI am trying to get PvPGN working... I have installed all the files, the only thing now is that bntrackd wants to use 'logs/bntrackd.log' for it's logfile, but seeing as it's in /usr/sbin, I want it to use /var/log/bntrackd. This is done with 'bntrackd --logfile=/var/log/bntrackd.log' but when I put that in the script it won't process it as a command (instead splitting it and complaining that I don't have --logfile=/var/log/bntrackd.log installed)

I am not sure If anybody has faced this issue, my keyboard is less responsive when pressing the double quote/single quote key, I have to press it twice for it to print the quote( and that too it prints some other data and not exactly a double-quotes). Initially I thought it was issue with my keyboard, but later I see that it is working fine in Windows XP. It looks some kind of setting issue. If you check the below two examples, example a) is the double quote printed in Ubuntu, it doesnt exactly looks like a double-quotes and b) is the one printed in Windows.

I am looking for a way to delete the currently entered commandline without wasting seconds on the "Backspace"-key.
For example I scrolled the bash history and have a long commandline that would execute when I pressed ENTER:
~$ aptitude search openssl | grep dev
But now I decide that I do not want to execute this command. Can I get an empty prompt fast without deleting the whole line with Backspace? On the Windows "cmd" you can just press ESCAPE and it is gone. This behavior would be what I want.
The question may seem trivial but this is bothering me for a long time now.
I am looking at how to add particular text to a file in bash.Here is what I am trying to do:In the /etc/grub.conf file, I am trying to add "audit=1" (without the quotes) to the end of the kernel line...such as:kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/1 rhgb quiet audit=1
As there are a few different lines in this file, I am only looking to add the "audit=1" to the above line via a bash script.
I have a lot a folders, each named by a number, and in each of these folders I have a specific file (stddev.dat) containing a single line (of numbers) I need to have a single file with each line being one of the stddev.dat (no matter if it is sorted or not), and also I need to add at the begining of each line the number of the folder it comes from.
I 'm no bash expert, and the "add at the begining of the line" is a bit of problem to me". Here is what I've come up with so far, just to put everything in one file, (and also if you know a better/more elegant way to do the same thing I've done, I'm listening)

I just installed ubuntu today, and it asked me to install over 200 security updates. When I finished that, it asked me to restart the computer so that the updates will take effect. After Dell (it's a Dell computer) booted, I got a message reading:
"Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else, TAB lists possible device or file completions."
I would like to know how do I print the line # in a script. My requirement is, I have a script which is about ~5000 lines long. If there are any errors happen I just exit. And I would like to add the line # of the script where the error happened.

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)

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.

The problem is that foo might return an empty string and if it does I need to catch it

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.)

The following script will work when I type the path to the file I want to checksum, but not when I drag the file to the terminal because the linux terminal (unlike the Mac) automatically puts quotes around the file path, which causes an error. I did not find anything in gconf-editor or anywhere else to alter this behaviour, and my post in Launchpad is unanswered so far. (the script in itself is not very useful, I just stumbled upon this error when experimenting with bash).
So, is there a workaround for stripping the quotes from the input, or can I configure the terminal to not quote the input when I drag a file into it (which I would prefer?)I am currently logged in from Mac OS, but the question refers to ubuntu karmic with which I dual boot.ADMINISTRATORS: Thanks for the quick reply to my newbie question about posting new threads. Actually I don't see now what the difficulty was; I guess I was tired from trying to debug the above script (not funny).
