Software :: Removing Line Terminators From A Plain Text File?
Jul 31, 2010
Linux kernel 2.6.21.5, Slackware 12.0.
I would like to know if it would be easy for me to get a program which, given a plain text file as input, discards the line separators and writes the rest as its output. And let's put in the case of a file that has been mangled to the point of having CR,LF (carriage return, line feed) in some places, only CR in others, and only LF in still other places. That is, the three possible combinations used in systems as a newline char (the 1st is, or was used by m$- dos, the 3rd one by Unix and I know systems where CR is the line terminator).
After all, all the program has to do is, every time it finds a char belonging to the set {CR, LF}, cast it away.

I've downloaded a file, by clicking a link, called errors.txt, which is a plain ascii file from the internet. In fact, the link isURL...>Go to List of errors>Click here for the text-only version of this site.When I click 'Click here for the text-only version of this site', file errors.txt opens in my browser's window (KDE) and I can perfectly read it. However, if I do File>Save as, then what I get is a file (errors.txt) with only (carriage return) as line terminators, and editors such as vim render a somewhat illegible presentation of the text.

I put a text file on my desktop and added a couple lines of text with gedit. File type shows text/plain. Double-click opens the file in gedit which is what I want. I'm using the file to temporarily hold some snips of code that I copy from file to file, but when I copy some html into the file and save it, now file properties show it's text/html and a double-click opens the file in firefox, which isn't what I want. Is there some way to keep the file type from changing itself?

I am looking for some source package which will convert plain text file to html file without using perl.
I mainly need to do this on an ARM platform, so if I get sources I can cross compile it.

Basically, I have a selection of .rdp shortcuts to various machines, but they are considered the file type "plain text document (text/plain)" so if I change it to open with to tsclient, all of that file type opens with tsclient. And if I change it to gedit, all the rdp files open with gedit. Is there a way to create a custom file type dependent on the extension rdp, or is there a way to set tsclient to open by extension rather than filetype?

i have a big file of random numbers i generated at some point in time, after working with it with different things(how fun that was)... i want to remove duplicate lines and i'm not sure i'm doing this right
heres the command
Code:
sort random.txt | uniq -u > rand-shorter.txt
the file is pretty big, everything on a new line. i found the command on a web site so i'm sure its correct(bit of a command line in linux newbie)
can anyone confirm if this will remove lines duplicate lines (keeping one copy) and dump what is left in a file named rand-shorter.txt?
EDIT: i think its actually working, just taking a reallllly long time (on an old pen 4 from 2000)

I just downloaded a Plain Text File that contains (what appears to me as) code that will 'unlock' functions of my MS keyboard, now what do I do with it? Here is a preview of some of the contents of the file from the beginning of the text.

.....and so on with different items. My goal in doing this was to enable the zoom button on the keyboard.

im trying to output a list of running processes via a shell script. At the moment i got this which outputs the processes to a text file called out.
echo $(ps aux) >>out
The problem is though, the processes are all just one big block of text which makes it hard to read. Does anyone know how to sort the output to a text file so that it prints to the text file at 1 process per line? I know its probably simple but im very new to linux.

I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

I have two txt files containing x and y coordinates: xcoord.txt & ycoord.txt. I need to open them; read them line by line to get each coordinate; then each time I need to update Xs and Ys parameters inside another file called "dc.in" with the grabbed values.
Finally each time I need to run two exe files ( dc_2002 and st_vac) and produce corresponding output for each Xs and Ys ( dc.in is an input file for this exe files)
I have written the following code but it does not work:

Was wondering if any perl guru's could help me with a quick log file adjustment. I have a text file that looks like so (tabs and newlines are revealed so you can see what separates the data):
There are maybe 100 lines of text in this file at any given time. I need to delete all duplicate lines only looking at the first bit of text prior to the first tab. It doesn't matter which one gets deleted as long as there are no two lines that begin with that same text at the beginning before the first tab. So in this example, either the fist line "1234" or the last line "1234" would need to be deleted. I already have code in my script that opens the files - I just need the code to read the text into an array and the part that would find matches based on the above criteria, and make the deletions.
If it would be easier, I can even do a system call and use SED (v4.1.5) and/or AWK (3.1.5) instead.

bash 3.1.17(2) I'm trying do write a shell script which must operate on each line of an ASCII text file. So, all the code must be inside a loop, and inside the loop, the first thing should be to read the next line from the file. I have the bash read command. But it reads from stdin. Any way to make read from a file?

I've been using openoffice.org a lot recently and I was hoping that I'd be able to cat the contents of the file solely through the terminal.What's the best way to do this? My thought is to use a command in a terminal to convert to plain text and cat the file.

With the gpg command I used to encrypt files so they saved as plain text (the encrypted files were viewable in a plain text editor though were a encrypted nightmare)
I just forget the option in the gpg command to do this and I can't find it in a hurry either in the man file

I'm new to the shell scripting. can any one help in creating shell script for matching the content of the specific variable with file. it should remove that line from the file if line is containing same value as variable and keep the other content as it is.i used grep -v for accomplishing the same. But grep will remove the pattern which is similar.For eg. Assume file "test" contain datas :aaffif i used grep -v command for the pattern "a" to this file this will remove content "aa" from the file. I want the pattern only "a" should remove from the file, if it is existing. otherwise it should throw alert content not exists.

Are there any Linux tools that will allow me to do this from the command line (so it can be scripted)?

I somehow managed to screw up my lucid lynx system so that all files show up under Nautilus properties as Type Plain Text. When I double click a file, any file, the system tries to open it as plain text with gedit. Everything worked correctly until yesterday when I tried to install a new version of PyQt4. If I reboot with an old (karmic) version of Ubuntu and bring up Nautilus Properties on the same file (my data partition can be opened in other OS's) the files show up with the correct file type (PDF, ODT, etc) So the problem is not in the file itself, but rather in the lucid OS, which is mis-interpreting the file type. As I said I somehow messed it up when installing the new version of PyQt4.

When I print receipts from certain company's emails, they span three pages or more bloated with images, links and overly large text. I can view the message in plain text by setting the preferences to only display text instead of html, but it doesn't affect what is printed. I still get the full HTML page printed. Is there a way to force evolution to print in plain text instead of HTML?

I was wondering if there is way to hide passwords in bash scripts. For example: I have to write a script to export a full ldap structure, and I'm using the ldapsearch -y passwordfile, where password file is a plain text file that contains the password. Is there a way to hide the password from that file?
I was thinking to remove the r attribute from the file and before the script is lunched to put the attribute back, but is not a good solution, the same with immutable attribute.

Since we switched our server to Squeeze, I'm receiving emails from the cron about a mysql error (...can't use locks with log tables). But this is not the issue I want to talk about here. The issue is that since the executed command is: /usr/bin/mysqlcheck -uroot -pmypassword --all-databases --check-only-changed --silent which is a command that was automatically added to the cron by the mysql package (I believe), the password is sent in clear text in the email's subject. In my sense, this is a serious security issue (sending root password in email subject...)
I don't know at what level it should be corrected, but it seems to me like it should be corrected in the Debian distrib, shouldn't it ?
And for now, how can I hide the password in the emails I receive ?

I'm trying to figure this error message out. This little script is supposed to tweet my laptop's IP address, as a cron job, I'm hopeful that it would do so even if it's stolen. This is a variant of one that works, but this doesn't, and I can't see a difference in the curl line of either one.
Code:
#!/bin/bash
user="xxxxxx@xxxxxxxxx"
pass="xxxxxxxxxxx"
wget [URL]
TWEET=`sed -n 1p index.html`
curl --basic --user "$user:$pass" --data-ascii "status=$TWEET" "[URL]"
rm -f index.html
exit
This is the error message.
Code:
curl: (6) Could not resolve host: status=66.183.103.67; Cannot allocate memory
{"request":"/statuses/update.json","error":"Client must provide a 'status' parameter with a value."}
Why does curl think the status is the URL?
