General :: Does Non-printing Characters Escape Characters Still Needed For PS1 Definition?
Aug 28, 2011While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?

Ubuntu :: Delete All ASCII Characters In File - Leave Chinese Characters Only
Jul 8, 2011What command could I use in terminal to delete all ASCII characters? That is, delete a-z, A-Z, 0-9, and all punctuation? I have a file containing Chinese characters, and I want to remove everything else and leave just the Chinese.
I can use grep to leave only the lines that have Chinese in them, but this still leaves a lot of non-Chinese stuff on those lines. Does anyone know how I could actually remove everything that isn't Chinese?

View 1 Replies View RelatedServer :: Uppercase Usernames In / Etc / Sudoers Triggers Warnings
Jan 6, 2010We're syncing users from Active Directory over to our linux LDAP server (Red Hat Directory Server). The user names on the AD side are all written in uppcase letters, which is the company policy.The uppername usernames causes problems when setting up /etc/sudoers, since uppercase words are interpreted as aliases. For example, if I add user KENNETH to a User_Alias (i.e. something like "User_Alias ADMINS = KENNETH"), I will get a warning from visudo which expects KENNETH to be an alias and thus not a username. Despite the warning, sudo does seem to work correctly. But is there a way to tell visudo or sudo that usernames are uppercase, and should not trigger a warning? Or are there other ways to go about this sort of thing?

Dec 29, 2010I often use VNC to connect to my desktop upstairs using a laptop downstairs over my home network. I tunnel the VNC connection via SSH. The problem I keep running into is that I'll attempt to type a ! or a : or even a captial A and it will come across the wire as a 1, ;, or a respectively. Is this something I can fix? It's really REALLY annoying while one is programming to have to pop open character map and find a colon and copy/paste it in each time. Running Ubuntu 10.04 upstairs, Linux Mint 10 downstairs.

General :: Keep Last 'n' Characters Of A Specified Field?
Apr 4, 2010The input file consists of several fields. The first field is always five or more characters long. I want to keep the last five characters of the first field.
Example:

General :: Get The Lines With Only Five Characters?
Nov 2, 2010I have a file with a random word on each line (3k+ lines). How can I get the lines with only five characters? I tried using grep file | more, but it returns all the words (even those less than 5 characters).
Edit: I also tried grep '.{5}' file | more but it doesn't show anything. And grep '.{5}' file | more returns all lines with four or more characters (I'm really confused about why it's doing this).
General :: Sed - Match Even Characters Only?
Sep 3, 2010Say I had a string like so
Let's say I only wanted to grab TAC and BDX the ones in the 2nd, 4th, and 6th spot.
Will grab the lines from the rest of the file assuming these are the only lines with capital letters at the very beginning of each line.
Will delete the first 'T'. What I want to do is learn how to just pick the even characters, T(T)A(A)C(C) & B(B)D(D)X(X).
Is there something like the {1} which can pick just the even or odd character matches?

View 1 Replies View RelatedGeneral :: How To Ignore Hidden Characters
Nov 3, 2010I'm trying to look at a file and find 6 or more consecutive consonants (everything except a vowel). However I have a hidden $ character at the end of each line in the file. For some reason I can't reference to it in any of the pattern searching commands.
For example: grep '[^aeiouAEIOU$]{6,}' file| more
This command returns words that contain 5 consonants at the end (because it interprets the hidden $ as not a vowel). How can I make it ignore the hidden character? Or more specifically how do I refer to the hidden character in my pattern searches?

General :: Error - BAD PASSWORD: It Does Not Contain Enough DIFFERENT Characters

Even though the passwords I'm trying seem pretty safe and complicated enough to me. I googled and think this is controlled by something called cracklib? Don't know for sure though. How can I change the settings for this, perhaps lowering the amount of different characters required, or disabling whatever security setting is causing this error?

234
5466
2356
... and so on.
but I would like this to change to 234,5466,2356,... I looked at sed and tried to wrap my head around the commands but I guess my brain isn't smart enough. its really confusing for me. I've managed to add commas to end of line (sed "s/$/,/g" filename) but somehow I can't seem to remove new line character from each line.
sed 's/[
]*$//' doesn't seem to work.
