got a situation where if i process a command i get a numeric output something like below:
for example:
# cat example.txt
856589
856470
987866
656658
876897
now i want to see this output in single line like below:
856589 856470 987866 656658 876897
how do i get this?
I need to create a single line of output from multiple and variable lines of input in a Linux bash shell script.
My input file looks like this:
Where there may be any number of umsecondaryphonenumber lines; if there is not a umsecondaryphonenumber line for a telephonenumber, I don't want to write any output.
So, the output file should look like:
The script I have so far is:

[root@yukiko /]# find / -iname .bashrc
/home/clamav/.bashrc

But I would like to have a command that prints a specific line by supplying the command with the line number, for example:

/home/vpopmail/.bashrc
Is there such a command on CentOS?

Ive seen some fixes for this but they all seem to be specific to the particular user's sources.list . . . ..
Code:
Here is Line 54

I tried to change the basic toolbar to cairo dock,a tutorial that i found told me to write in terminal gksu gedit /etc/apt/sources.list.d/winehq.listso i write it and a window opened,i couled not find the text that told me(the tutorial i mean)so i closed the window,after that i keep taiking the same error
E: Type �sudo� is not known on line 55 in source list /etc/apt/sources.list
E: The list of sources could not be read.
Go to the repository dialogue to correct the problem.
E: _cache->open() failed, please report.
now whene i got in the winehq.list the text has gone and i take this error in update manager,my software center doesn't work and my terminal whenever i type sudo commands says
E: Type �sudo� is not known on line 55 in source list /etc/apt/sources.list
I get this error message: E: Malformed line 57 in source list /etc/apt/sources.list (dist parse)
I am pretty new to Ubuntu and dont really understand computer
Here is the sources list (??) as well
don't know much, but when I tried to update I get this error:
E: Type 'sudo' is not known on line 52 in source list /etc/apt/sources.list E: The list of sources could not be read.
The objective is to read a file line by line, add a tab at end of each line and add a value(number) after the tab.
My script:
Code:
Report.tsv before running the script for the first time:
Code:
At the end of first run, each line of Report.tsv gets appended by a space instead of a tab. On the other hand each line of Report.tsv gets appended by tab at the end of second run onwards.
This was realized when Report.tsv was imported in open office spreadsheet. First set of appended values get merged into the original column (Strings) and the subsequent appended values fall in distinct columns.
There is a problem with my source list (apparently) I'm running 11.04 if that helps.When I try to use apt-get install update for example, I get: "Malformed line 59 in source list etc/apt/sources.list"The same error occurs when trying to access synaptic package manager, it tells me there is a malformed line and the list of sources cannot be read.This error prevents me from apt-getting anything, updating and i suspect it is affecting the software center too.

1 aaaaa bbbbbb ccccc

If I grep -nr sumthin * in my source code directory, it also spews out very long lines from minified JavaScript or CSS files. I want to get just the first 80 characters per line. For example, a regular grep gives me this:
css/style.css:21:behavior: url("css/iepngfix.htc")
css/style-min.css:4:.arrow1{cursor:pointer;position:absolute;left:5px;bottom:10px;z-index:13;}.arrow2{cursor:pointer;position:absolute;right:5px;bottom:10px;z-index:13;}.calendarModule{z-index:100;}.calendarFooterContainer{height:25px;text-align:center;width:100%!important;z-index:15;position:relative;font-size:15px!important;padding:-2px 0 3px 0;clear:both!important;border-left:1px solid #CCC;border-right:1px ... etc.
But I'd like to get just this instead:

I'm trying to make another file annotation script a little speedier than it has been by the up-until-now proven method of checking the last four characters in a filename before the "dot" (eg .jpg, .psd) against a list of known IPTC categories and Exiv2 command files. It occurred to me that if one script generated a list of files in directory foo, and the same or another script sorted that list by that four-letter tag,then that list could be used(instead of a for/do/done loop on the real files in the folder) by the command-file-matching script to "vomit out" which annotator file would go with file nastynewfile.jpg, f'r'instance. The script I had been using for this task looks like this:
Code:
while read 'line';
do
sp=$(echo $line)
vc=$(echo $sp | cut -d"," -f1)
cv=$(echo $sp | cut -d"," -f2)

Where I seem to be stuck is with how to sort the lines in templist, which may be any number of different lengths, from back to front. sort -k looked promising, except it seems only to work the other way round. I thought of invoking a
Code:
q=$(expr length $line); echo $q
n=$[q-8]; echo $n
kind of thing, but that presented the problems of how to sort by those, how to tell sort where to find them (grep?) and how to "stitch them back in" to the original list, which is what I want to sort in the first place.
I'm trying to remotely run a script on a target machine though the ssh command-line using passwordless login. I know the keys are set up correctly because if I remove the call to the script, the ssh session succeeds and I can log into the remote machine, but when I call the csh script, I don't get any output on the command line. If I call an identical bash script, I do get the output. Specifically, calling line 1 below just returns me to the command line, but running line 2 echo's hello then returns to the command line (both scripts simply contain a single line to echo hello, and both work when run locally on the remote machine). Why do my csh scripts send any output through the ssh link whereas the bash does?
Code:
1) ssh -i /root/.ssh/id_rsa user@remotemachine /tmp/test.csh
2) ssh -i /root/.ssh/id_rsa user@remotemachine /tmp/test.bash Update: I have further determined that nothing I add to the csh gets run either. I've tried touching files and making directories in the scripts, and all gets run using the bash script, but calling the csh script like line 1 above does nothing, nothing is touched or created.

Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
