saini_mw · 02-01-2011, 09:59 AM

Hello Guys!

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??

Thanks in advance.

Use 'tr' to replace newlines with spaces

Code:

cat example.txt | tr '\n' ' '

(That \n may need to be a a \r, I can never remember)

i think this would do it

Code:

var="`cat example.txt`"
echo var = $var

Code:

$ ruby -ne 'print "#{$_.chomp} "' file

cat example.txt | tr '\n' ' '
856589 856470 987866 656658 876897 [root@host tmp]#

it prints the "[root@host tmp]#" on the same line. is there anyway that i can issue a new line after that???

same issue with "tr '\n' ' ' < example.txt"

Code:

echo ''

Wouldn't be complete without an awk entry:

Code:

awk '1;END{print "\n"}' ORS=" " file

perl to the rescue

Code:

perl -pe 's/\s*$/ /' sample.txt
