I have a text file that each contains either a domain or an IP, like this:
Code:
[me@server ~]# cat file1
122.foo.com
yahoo.com
23345229.com
[code]....
I want to remove all IPs in that file and keep others, so the result be like:
Code:
[me@server ~]# cat file2
122.foo.com
yahoo.com
23345229.com
[code]....
For some reason it seems like my Thunderbird 3.x has a limit of 80 chars per line enabled, so when I edit a message, it puts a line feed on or before that limit.
I think it could be set when I installed Enigmail for using GPG, that changes some default values, but I'm not sure.
Anyway I would like to avoid this issue, so I can write lines as long as I want, but I've not found a configuration option to do this within "Preferences" dialog.
I know how to use grep to output a line that matches a string. But what if I also want to output one line above every line containing a matching string, how do I do that?

The problem with uniq is that the last two colums will differ. I don't care about the x/y for any points following the first one.
I have a txt file with couple of comment lines:
Number of title = !num!
#line1
#line2
#line3
I wrote a script with "sed" to replace !num! in this file, which is very straightforward. However, based on the !num!, I want to remove the number of "#" based on the !num! value. Is there an easy way to do that with "sed"; otherwise, i will have to write a script to loop through the file.
When i want to remove particular lines containing a specific word in from entire document at a time,i am using the following command.
awk '$columnno !~/specificword/' inputfile > outputfile
But here, coulmn no is my problem, because iam having this in different columns. So i need a solution for it.
How to write such removal command without mentioning column no. , ie irrespective of column no, it has to remove all lines having that specific word.
Is there any commands or scripts to remove only selected line in the history file.

I want to be able to remove the first character of a line when I highlight multiple lines in gedit. Example:
%Example is
%Commented Code
%Uncomment using this shortcut
I would then highlight/select these lines, and remove the first character to make it look like this:
Example is
Commented Code
Uncomment using this shortcut
I'm pretty sure there is an actual shortcut for this. If there is another text editor on Linux that it would work in, it would be nice to know how to do it in that editor as well.

View 2 Replies View RelatedYears ago on AIX I used to create a file of key strokes, including function keys (mainly F3 and F12) into a file, and used that file as input to an INFORMIX program, to automated tasks, something like this:
fglgo myprogram.fgo <keystrokefile.txt
Now, I'm using Aubit language on GNU/Linux, and I'd like to do the same kind of thing, but I can't recall how I worked out the chars for the function keys, I'm using a different emulation (xterm), and I can't work out what characters to put in the key stroke file. My $TERM variable contains "xterm". If I type "infocmp", I get this:
Code:
# Reconstructed via infocmp from file: /usr/share/terminfo/x/xterm
xterm|xterm terminal emulator (X Window System),

[Code]....
1. Is the above infocmp output the place I should get the information I need?
2. What chars do I need to put into my file to simulate me pressing F3 and F12?
3. Is there a way for me to put such chars in a file by just pressing those function keys (I tried a here document, but that doesn't work (it's as if the function keys are not even pressed)).
I have an application where the client is written in Visual Studio (C#), run on PCs, and the server end has traditionally been SCO. We're now migrating to Linux. I can, for example, input "Test This" in a text box on the client, and when the server end is SCO, it is able to 'accept' the character sent to it from the client. When I try this same example on Linux, that character (hex D1) does not 'make it' from the client to the server.
The problem is not on the client, and I have verified that the telnet connection is in fact passing these extended characters, but they are not recognized properly by the Linux server.In researching this, I've played with setting the LANG environmental variable from LANG=en_US.UTF-8 to several of the other possible values found in /usr/lib/locale, for a european locale (the end user is actually in Spain), and these 'euro' characters are still not handled properly in my application.Would anyone be able to point me to any specific env variable settings, and/or anything else that would resolve this issue?
Suppose I'm editing a file with vim. The file, a text file, contains line terninators which are line feeds (LF= 0x0a). It could also contain horizontal tabs (HT= 0x09) and some more non-printable chars (in fact, it could be corrupt and contain anything). Will vim let me see the location within the text of those chars (chars = characters) and what each of them is? I know there are such things as hexdump and the like but it would be nice for me to stay within the vim session.

After that I execute all the scripts in sqlplus, and in one or two of them I get an error: SP2-0042: unknown command ")" - rest of line ignored. If I open the file with vi, I can see that in the end of each line there's a "^M", which is treated as a single character. If I delete this character placed before the closing parenthesis, the scripts executes without any errors. In the initial script opened by vi there's no such characters. Is it a problem with the head utility or with something else? Of course, I cannot grep these special chars.

I'm trying to come up with ideas for a simple way to strip a specific "entry" from a text file.I know tools like sed and perl can remove specific lines from a file but I haven't been able to come up with an elegant way to do my group of lines.In my file, the first "Location" line and the "SVNPath" line should be unique every time... but are they enough to strip out the whole set of the group plus the trailing one line of white space separating each group? Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
