I have a file partially like this
209 c 89
215 a 76
603 B 190
626 f 240
I want to separate this file into two sub-files based on the lowercase and uppercase of column 2 so that the sub-files are like
file1
209 c 89
215 a 76
626 f 240
file2
603 B 190

As a result of having mixed files from different filesystems, I have, in directory foo/, files with filenames in uppercase and files with filenames in lowercase. If I want to convert them to all uppercase how do I do it? Consider this will be later recorded into optical discs.
I'm trying to convert all file extensions for files in many sub-directories from uppercase to lowercase. I have two problems, how to list the absolute path to the files recursively over many sub-directories for which I so far have this:-
Code:
find ~/Photos -print which would be fine, except it gives the directories on their own when it finds them rather than just the files with absolute paths. I couldn't find a switch for the "ls" command to do this, so I had to improvise with "find". and once I get grab each absolute file name, to just change the file extension rather than the entire file, which is what I have at the moment.

I have quite a strange issue with (supposedly) my keyboard mappings.
while using GNOME session:
lowercase 'v' is not working as it should - no keypress is reaching apps; while I'm holding V key depressed, gnome-terminal console shows a hollow cursor (just like when input focus is in some other window) and nothing is printed; uppercase 'V' is working just fine (that is Shift+V); if I press AltGr + V, a lowercase 'v' is printed; if I'm typing quickly, sometimes pressing V key to get a lowercase 'v' is not just being ignored, but also the next symbol typed is swallowed and not printed out; this issue is present for the USA keyboard layout, as well as for the Russian keyboard layout.
while using TTY console (Alt+Ctrl+F1, etc):
everything works as it should (i.e. lowercase ' is printed whenever I press it);
no problems with the physical keyboard.
I haven't done any editing of any gnome/X configs and/or keyboard mappings.

I would love to see if there is a way in linux that if I have forgotten the command name and would like the search the entire root using "find" command but I am not sure of the case sensative of the command name (eg. VBoxManager or vboxmanager). So how can I search the root with everything treated as lowercase first? or is there a regular expression to search?

I'm trying to learn to rename files with the command line, and after browsing around a lot of pages I finally found a command that uppercases the first letter of a file, but the problem is that I want to understand the meaning of each command. The command is:
for i in *; do new=`echo "$i" | sed -e 's/^./U&/'`; mv "$i" "$new";done
I understand the 'for' kinda... but not the 'echo' or '`' and especially the sed command.
I made a bzip2 file by
bzip2 -c /home/os/picture1 > /home/os/Desktop/pic.image
bzip2 -c /home/os/picture2 >> /home/os/Desktop/pic.image
But now extracting pic.image by bzip2 -d /home/os/Desktop/pic.image returns
bzip2: Can't guess original name for pic.image -- using pic.image.out
And then it just creates one file pic.image.out.
How do I access picture1 and picture2 from pic.image?
What is the general feeling for the case of hostnames in Linux/UNIX, is it preferable to have them in lower-case or upper-case? I have always preferred them as lower-case but I am interested to see if there are any arguments for or against this practice.

Because the two positions are separate, I do not want to Import his Evolution over my own - but, I do want to be able to access it from my machine. Can my Evolution refer to the old hard drive (now in a caddy and non-bootable) for the Evolution account data that is there, while still being able to switch back to my own Evolution data on demand. E.G. in Windows the equivalent would be the way that Outlook can refer to different .pst files at loading. Alternatively, can I make the external USB drive (previously a running main HDD) bootable without losing all of the data?

I don't know, however, how to create a DVD such that each of the original .avi files will be their own chapters. In other words, I have about six or seven .avi files (episodes of a season of a television show) and I want to create a DVD with those episodes that I can navigate separately. Do I first convert each .avi? How then do I create a single DVD with six or seven chapters/episodes?

View 3 Replies View RelatedFor some reason, just shortly ago, the terminals, konsole, etc. will not accept the lowercase letter 'e' as input for some reason, not even when pasting, e.g.
a paste of file:///usr/share/applications/kde4/konsole.desktop
becomes fil:///usr/shar/applications/kd4/konsol.dsktop
on the command line. Weird.
For everything else I have tried at this point on the computer, the lowercase letter 'e' is just fine (this message being an example);Has some configuration file for terminals (konsole, xterm, Yakuake) or whatever got messed up and I need to correct it?
A few minutes ago, without any apparent reason, my gnome-terminal started refusing acceptance of lowercase 'L'. When I hit the 'L' key, the menu toggles between visible and hidden. Note, this is lower case 'L', not uppercase.

View 1 Replies View RelatedRunning Red Hat (not sure of the build atm) and I need to be able to put all of the IP blocking in a separate file. It will eventually be uploaded to a large number of hosting accounts, and modified from time to time...so it isn't feasible to modify that many httpd.conf files each time we need to add an IP to be blocked. In httpd.conf I can add the "Deny from" line to the following directive and blocks it just fine:

# Possible values for the Options directive are "None", "All",

There is an include to pick up all *conf files in ../conf.d, and everything else in there is working just fine. I created a file called robots.conf; it currently has a set of mod_rewrite rules which work. So I added this to that file:
Code:
<Directory "/var/www/html">
Order allow,deny
Allow from all
Deny from 123.456.789.098
</Directory>
It is not blocking access from the IP with it in there.I've done all of the usual things; restarted Apache, cleared browser cache etc. I can also block it using that same directive in a local .htaccess.
I have two files containing list of packages using

Now I would like to create a third file which contains only those packages which are present in package-a.txt but NOT in package-b.txt. The file should look like this:
Code:
package2
package4

package2 install <

I'm working on changing some badly named files, lots of them. I have a little script I use to change uppercase to lowercase:
[Code]....
Bear in mind all these files have appropriate numbers in the front of each filename. I need help to change ONLY the first letter after each underscore to an uppercase letter. I'm sure this can be done but I've done so much searching in forums and with Google/linux until I'm scrambled.
I have users created in Linux box with lowercase name, from one of my DB team from AS400 server they are trying to run a script from which they could only pass usernames only in "uppercase".
my question is how to allow the username if it comes in uppercase in linux (note: lowercase user shhudnt be changed to uppercase as well we shudnt add new user in uppercase)
