Hello guys,
i want to have those lines joined to one line with spaces
Before :
textone texttwo something
After :
textone texttwo something
So far i have been using fmt -w 2000 , but this is limited to 2000 characters. There must be something better.
Thanks in advance!
David

Use vi - commands gqap

J will only join two lines, although you could use 20000J (although you need the number of linnes correct). gqap will be better I think.

Hi David,
It's unclear if you want to do this interactively or from the command line, and whether you want to affect all lines or just selected ones. If you want to put all of the lines in a file onto one, you could use:
tr "\012" " " # convert newlines to spaces
-Chris
echo 'textone texttwo something'|xargs textone texttwo something

'cat' will not remove newlines.

Agreed.

Not by itself, but its a reasonable thing to run in backticks so the shell will do it for you:
echo `cat multi_line_file` or echo $(cat multi_line_file`) if you prefer that syntax.
Well i need it for script written in bash .
Thanks

Not by itself, but its a reasonable thing to run in backticks so the shell will do it for you:
echo `cat multi_line_file` or echo $(cat multi_line_file`)
Or to avoid the fork & exec:
echo $(<multi_line_file)

But you will end up with problems with the number of arguments on a command line if multi_line_file is too large.
How about:
cat multi_line_file | xargs
Note that the default command for xargs is echo
Or, to avoid a "useless use of cat" award (see http://partmaps.org/era/unix/award.html):
xargs < multi_line_file

Alas, that doesn't solve the problem with the excessive number/length of arguments either, because xargs will execute the echo multiple times if necessary to keep within the arg limits, potentially generating newlines in the output.
...Which is why I like the translate I proposed earlier:
tr "\012" " " <multi_line_file
