'echo' without newline in a shell script
I have a problem with echo in my script:
echo -n "Some string..."
prints
-n Some string...
and moves to the next line. In the console it's working correcly without newline:
Some string...
There are multiple versions of the echo command, with different behaviors. Apparently the shell used for your script uses a version that doesn't recognize -n .
The printf command has much more consistent behavior. echo is fine for simple things like echo hello , but I suggest using printf for anything more complicated.
What system are you on, and what shell does your script use?
bash has a "built-in" command called "echo":
$ type echo
echo is a shell builtin
Additionally, there is an "echo" command that is a proper executable (that is, the shell forks and execs /bin/echo , as opposed to interpreting echo and executing it):
$ ls -l /bin/echo
-rwxr-xr-x 1 root root 22856 Jul 21 2011 /bin/echo
The behavior of either echo 's WRT to c and -n varies. Your best bet is to use printf , which is available on four different *NIX flavors that I looked at:
$ printf "a line without trailing linefeed"
$ printf "a line with trailing linefeedn"
Try with
echo -e "Some string...c"
It works for me as expected (as I understood from your question).
Note that I got this information from the man page. The man page also notes the shell may have its own version of echo , and I am not sure if bash has its own version.
