How do I remove newlines from a text file?

Question

Hey there everyone ... I have the following data, and I need to put it all into one line...

I have this:

22791

;

14336

;

22821

;

34653

;

21491

;

25522

;

33238

;

I need this: 22791;14336;22821;34653;21491;25522;33238;

If anyone could help me it would be a great !!

Thanks in advance!

--------- EDIT

No of these commands is working perfectly...

most of them let the data like this:

22791

;14336

;22821

;34653

;21491

;25522

Thanks for the help. But if someone can solve this problem it's going to be really good!

Solved:

cat inputFile | tr -d "\n\r" > outputFile

Answer 1

tr -d '\n' < file.txt

Or

awk '{ printf "%s", $0 }' file.txt

Or

sed ':a;N;$!ba;s/\n//g' file.txt

This page here has a bunch of other methods to remove newlines.

Answer 2

tr -d '\n' < yourfile.txt

Edit:

If none of the commands posted here are working, then you have something other than a newline separating your fields. Possibly you have DOS/Windows line endings in the file (although I would expect the Perl solutions to work even in that case)?

Try:

tr -d "\n\r" < yourfile.txt

If that doesn't work then you're going to have to inspect your file more closely (e.g. in a hex editor) to find out what characters are actually in there that you want to remove.

Answer 3

$ perl -0777 -pe 's/\n+//g' input >output

$ perl -0777 -pe 'tr/\n//d' input >output

Answer 4

paste -sd "" file.txt

Answer 5

I would do it with awk, e.g.

awk '/[0-9]+/ { a = a $0 ";" } END { print a }' file.txt

(a disadvantage is that a is "accumulated" in memory).

EDIT

Forgot about printf! So also

awk '/[0-9]+/ { printf "%s;", $0 }' file.txt

or likely better, what it was already given in the other ans using awk.

Answer 6

If the data is in file.txt, then:

echo $(<file.txt) | tr -d ' '

The '$(<file.txt)' reads the file and gives the contents as a series of words which 'echo' then echoes with a space between them. The 'tr' command then deletes any spaces:

22791;14336;22821;34653;21491;25522;33238;

Answer 7

Using man 1 ed:

# cf. http://wiki.bash-hackers.org/doku.php?id=howto:edit-ed 
ed -s file <<< $'1,$j\n,p'  # print to stdout 
ed -s file <<< $'1,$j\nwq'  # in-place edit

Answer 8

perl -p -i -e 's/[\n\r\R\Zl]//g;' filename

Must do the job.

Answer 9

sed 's/\n//g' file
