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

......

i am expecting to cat them in to a single line to send by URL like: @china:129.00@uk:219.98@USA:341.90

i use echo cat eg_*

it give me the output look like a string, but it actually contains new line: "@china:129.00

@uk:219.98 @USA:341.90"

is there any other way i can construct that string which expected and get rid of new line and even the space? is only cat enough to do this?

thanks in advance

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)
