howto join lines

[David Hláčik]

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

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

[Dave Burns]

echo 'textone
texttwo
something'|xargs
textone texttwo something

the good old command line "cat" was invented (I am told) to
concatenate!

'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.

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

is slightly more elegant. Of course this assumes the file is ASCII or
similar.
