concatenating strings in shell 1

[DaveC426913]

Clearly I don't know how to concatenate in shell script.


#!/usr/local/bin/bash
FOO1="foobie"
BAR1="bar"
echo "$FOO1/$BAR1"
#exit 0


I want it to output foobie/bar
What I'm getting is /barie

#!/bin/bash
FOO1="foobie"
BAR1="bar"
echo "$FOO1/$BAR1"
echo $FOO1/$BAR1

both work for me.

REALLY??

You're typing sh test.sh at the prompt, and it spits out
foobie/bar?

 

[DaveC426913]

Could this possibly be some server setting?

And what about this ?
/bin/echo "$FOO1/$BAR1"

Hope This Helps, PH.

That isn't going to slove the problem, this fails too:

BOB=$FOO$BAR
echo $BOB

This outputs the same thing (/barie), so it's nothing to do with the echo command itself.

I've been experimenting with simpler versions:

#!/usr/local/bin/bash
FOO="foobie"
BAR="bar"
BOB=$FOO$BAR
echo $BOB
#exit 0


This produces barbie (no funny comments!)

There is definitely something scwewy going on here...

Well, this is a fun one.
I can MAKE that symptom happen:

$ more doit
#!/bin/bash
FOO1="foobie^M"
BAR1="bar"
echo "$FOO1/$BAR1"

$ ./doit
/barie

Is there ANY possibility your $FOO1 variable has a control code embedded?

I have just used Webmin to create a new doc and typed in the code from scratch. Thus it cannot have control codes in it. Exact same result.

If anyone would like to try the file I created, I've uploaded it here:

I downloaded your test script. Ran it, and got your results. Then, I removed the trailing ^M (Carriage Returns) from each line and got the desired results.

You should have a "dos2unix" type conversion script on your system. If not, use "vi" to remove those trailing ^M characters and try again.

Sigh. The editor I'm working in (Webmin File Manager Java Applet) has a little checkbox: DOS mode. It was checked. Unchecking it drops the extraneous carriage return from the end of each line.

You can see what my app was doing now. The variable $FOO actually was being populated with "foooo"+CR


Thanks all.
