I've copied a bunch of text into vim and I need to get rid of the line breaks. I've tried
:%s/^M// (where ^M is C-v C-m)
and
:%s/.$//
and
[code]....
all lines are terminated with a '$'. How can I get rid of them?
I have a CSV file that's created in an application that can't output lines longer than 250 characters. the data fields, all together, are longer than this. how would I remove the line break from every line that ends with a comma? For example:
A,B,C
D,E,
F
G,H,I
becomes:
A,B,C
D,E,F
G,H,I
I have some text files (Just plain text files, not OpenOffice files or anything) and when I try to open them in Windows they are all one line. I think I read somewhere that Linux uses for new lines whereas Windows uses or something... I am using Kate to edit them, and I have a LOT of files to fix so...
View 9 Replies View RelatedI configured ( sendmail + Smarthost + pop-before-smtp settings + smtp auth settigns ), today i saw 18000 mail in mailq and somebody sending mail from my mailserver ,as i got reported by ISP for spaming. How someone broke the sendmail + pop-before-smtp settings. i usually access that system through webmin. Is webmin cause to hack password.
Or How someone break sendmail security without even choosing my own user / password spamper settings messages to smart hosts to yahoo / gmail with his own junk user name and password? I stopped sendmail for the time being. Any idea what i should look for and what i should go for its remediation?
I can't seem to find any info on a terminal command that lists the contents of a directory with page breaks so that I can view the contents of a very large folder (such as /usr/bin) because if I use ls, it prints so many names that scrolling up won't even cover all of them. We all know the obvious solution is to use a graphical file browser, but I tend to shy away from depending on graphical utilities simply because command line feels faster.
View 3 Replies View RelatedI have a hard drive with a bad PCB board. It stays on when not under heavy load and it will restart if I copy too much data off it. So far I have had good luck doing folders under 500 MB in size if I copy one folder to my good hard drive, wait five minutes, copy another, etc.
If I mount the bad drive and try to copy a folder of several GBs in size it will start and then stop as the hard drive restarts. When I try to mount the drive again Linux says it can't read the superblock. I have several folders with over 30 GB of data in many different folders.
What I am looking for is a way of copying a folder in Linux such that the commands grab the whole folder in chunks with a timed break in-between.
I have formatted a second internal drive as ext3. It worked fine until I copied (rsynch) my /home to the new drive. Now when I try to delete anything I'm forced to delete immediately or skip the deletion. I also tried moving the /usr/local directory to the second drive and it works fine, it doesn't break the Trash. I tried moving /home back to the root drive and the problem is gone. The second drive again works properly. I can reproduce this. The problem only occurs when I move the /home directory to the new drive.

I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.
I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.

I am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test
hello my name is
b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test
b1a:] cat test
b1a:] hello my name is
Bob
b1a:]
So what I would prefer is some command that would create the result:
hello my name is Bob

I am using xterm and sometimes when typing long commands into a small window, the command extends beyond the end of the line. On my old uni setup, when this happens, the cursor moves to the line below and you can see what text you have typed above however on my slack 13 setup, it overwrites the current line so you cannot see what you have typed! How can I set xterm to move onto the next line instead of overtyping?

but if sometimes there could be extra empty line, then add at the empty line. So the script needs to detect whether or not the last line is empty. i figured out the symbol for a new line pattern is ^ so it would probably be sed "a^stuff here"is this right? but i dont seem to get the right result

I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.

Here is the code but it compares only first line of files..but it should compare the whole file1..and sorry iam a beginner in C can any1 sujest some modification to this code so that..it can compare file2 with entire file1
