 Posted: Sun Jul 05, 2015 3:42 pm Post subject: bash strange behaviour printing \n character |
 |
|
Using /bin/sh I get the right behavior:
| Code: | $ echo "hello\nworld"
hello\nworld
$ echo -e "hello\nworld"
hello
world
$ |
However in bash I get this weird behaviour:
| Code: |
$ echo "hello\nworld"
world"hello\nworld
$ echo -e "hello\nworld"
world"hello
world
$ |
However, redirecting the output to a file works fine
| Code: | $ echo -e "hello\nworld" > hello.txt && cat hello.txt
world" > hello.txthello
world
$ |
Does anyone know what's going on? |

What is /bin/sh symlinked to? Report the output ofand the output of | Code: | | set | egrep 'TERM|BASH_VERSION' |
please.
For what it's worth, sh and bash behave the same (and apparently correctly) here, which is expected as sh is symlinked to bash.

Yeah I forgot to say that it's strange cause my default shell is bash!
| Code: |
$ ls -ld `which sh`
lrwxrwxrwx 1 root root 4 May 24 07:45 /bin/sh -> bash

Okay, good. So the only difference between your environment and mine is that I'm running konsole but you're running rxvt-unicode, so I'm afraid this is a display artifact bug with rxvt-unicode. Further evidence is that the content of files ends up correct always; in other words, bash works correctly when rxvt-unicode is out of the picture.

I've done a little experimentation and have not been able to reproduce your issue. Could you post the output of | Code: | | emerge -1vp rxvt-unicode |
so we can see exactly which USE flags you built with?

Sorry for the very long delay in replying, I sort of solved my original problem avoiding this issue. I indeed suspect this is an rxvt-unicode issue. I'll try to post this in their bugzilla.
| Code: | $ emerge -1vp rxvt-unicode
[ebuild R ] x11-terms/rxvt-unicode-9.21::gentoo USE="256-color focused-urgency font-styles mousewheel perl pixbuf vanilla xft -alt-font-width -blink -buffer-on-clear -fading-colors -iso14755 -secondary-wheel -startup-notification -unicode3 -wcwidth" 0 KiB
