bash cat multiple files content in to single string without newlines

Question

i got some files with name start as eg_. and only each contains one single line

eg_01.txt: @china:129.00

eg_02.txt @uk:219.98

eg_03.txt @USA:341.90

Answer 1

You could always pipe it to tr

tr "\n" " "

That removes all newlines on stdin and replaces them with spaces

EDIT: as suggested by Bart Sas, you could also remove newlines with tr -d

tr -d "\n"

(note: just specifying an empty string to tr for the second argument won't do)

Answer 2

In Perl, you'd do it like this:

perl -pe'chomp' eg*.txt

The -p says "loop through the input file and do whatever code is specified by the -e switch. The chomp in Perl says "Remove any trailing newlines."

Answer 3

Using only one command

url=$(awk '{printf "%s",$0}' eg*)
