Can I dereference a wildcard in a command?For example if I want to create a file with the md5 hashes of compressed versions of files in a directory...gzip -rc ./source/* | md5sum -b - >> hash.txtThis above command gives me a file with one hash for the filename *I would like to get a file with the hashes and filenames for every file gzip compresses.
View 1 RepliesI need a command to search for any file in a directory like so:
/home/*/upload/* and then change permissions any file in that directory.
Find doesn't seem to match what I need.
I have some mp3 files with the wrong date stamp on them. I need to change the month value to May, and the Day needs to be changed from 6 to 4. For some reason my mp3 recorder messed the datestamps up. The time part is fine. I have changed the first three files to the correct MMDD parts, using the following touch command:
Code:
[root@karsites 04-may]# touch -t 05040253 REC066.MP3
[root@karsites 04-may]# ls -l REC066*

passing a wild card array to cp, I know it can be done but cant figure it out, ive got 3 files all start with the word somefile but have 3 different extensions
somefile.conf
somefile.dat
somefile.py
there in a folder with a bunch of other files and I just want to copy them to a different location. I remember is being something like cp somefile.[py conf dat] /somewhere but this isn't working Ive searched the net and can't find it with the keywords i'm using.
I would like help with modifying the following content:
toolbox/perl/man/man3/ExtUtils::Command.3::Command.3 differ
toolbox/perl/man/man3/ExtUtils::Command::MM.3::Command::MM.3 differ
I would like the content to be changed to:
toolbox/perl/man/man3/ExtUtils::Command.3

I have 2 massive duplicate dirs of the same format as below:
dir1
subdir1
file1
subdir2
file1
subdir3
file1
...
Dir2 is the same, but it has some newer files of the same name. I want to copy all file1's from Dir2 to the same name and folders in dir1. So basically something like:
cp -pr bkpDir1/*/*-big.gif Dir2/*/*-big.gif
This works for singular cases:
cp -pr bkpDir1/uniquesubdir/*-big.gif Dir2/uniquesubdir/*-big.gif
But not for wildcards:
cp -pr bkpDir1/subdir*/*-big.gif Dir2/subdir*/*-big.gif
Anyway the aim is to do the first cp above, I have tried a few options using find. In trying to show an example stumbled upon a way that worked, while in dir2:
find */*-big.gif | xargs -i cp -rp {} ../dir1/{}
Sure there are better ways also...

View 4 Replies View Relatedif I've missed this in the doc's, but I don't see the ability to "wildcard" blacklist for packages to _not_ be changed out via the slackpkg program.More specifically, I tagged all my packages like this:
mozilla-firefox-3.6b4-i486-1_OLDFOGIE.tgz
note the "OLDFOGIE" in my package name? So can something such as:
Quote:
*OLDFOGIE*
be put into slackpkg blacklist file?
Out of the box, Bash in 10.04 is configured such that it won't expand/complete parameters when there's a single match for a parameter with a leading wildcard. For example, if I have the following files in a directory:
Code:
ABC.bin
DEF.bin
GHI.bin
...and I type cp *E*, I expect to be able to press TAB and have Bash expand *E* to DEF.bin, since that's the only file in the directory with a capital E in its name.
(Note: if I actually submit the command with the wildcards in place, the correct file will be used then, but I don't get to see it beforehand.) I imagine there's something in /etc/bash_completion that's preventing this from working properly. Does anyone know what it is?
I'm using Apache 2.2 to host multiple subdomains using a single SSL certificate (a wildcard certificate e.g. *.mydomain.com) and, yes, it works! Everything seems to be served correctly and the browsers are pretty happy.
And you can also have the non-SSL sites (virtual hosts on port 80) on the same IP. (That's covered elsewhere)
For those that want similar functionality here's my discovery...
My configuration is like this:
ssl.conf:
Code:
I would have to say that I don't believe that this will work if you are not using a wildcard SSL certificate and having anything other than subdomains under that wildcard.
It is somewhat limited in scenario where this is useful, but for a set of company websites that should be under SSL, this can be tremedously useful when you have a single IP.
Here's my current regular expression(used in sed):sed 's///!Start.*//!End//g' in > outThe only problem being that the wildcard . does not work across multiple lines,

I want to be able to use Ctrl+R to have reverse-i search. Also if I press Shift+Up Arrow after typing the first few characters of a recently executed command then the shell should complete the command by finding the most recent commmand having the same first few characters.
View 1 Replies View RelatedBash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.
View 4 Replies View Relatedi'm trying to redirect the output of a command to the input of the next command. not sure if i'm going about this the right way. an easy method would be just to store the output of the previous command in a file and redirect input to read that file, but i'm curious to see if this can be done without writing to any files.

View 4 Replies View RelatedUp until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else
