Bash: Syntax error: redirection unexpected

Question

I do this in a script:

read direc <<< $(basename `pwd`)

and I get:

Syntax error: redirection unexpected

in an ubuntu machine

/bin/bash --version
GNU bash, version 4.0.33(1)-release (x86_64-pc-linux-gnu)

while I do not get this error in another suse machine:

/bin/bash --version
GNU bash, version 3.2.39(1)-release (x86_64-suse-linux-gnu)
Copyright (C) 2007 Free Software Foundation, Inc.

Why the error?

Thanks

Answer 1

Does your script reference /bin/bash or /bin/sh in its hash bang line? The default system shell in Ubuntu is dash, not bash, so if you have #!/bin/sh then your script will be using a different shell than you expect. Dash does not have the <<< redirection operator.

Answer 2

do it the simpler way,

direc=$(basename `pwd`)

Or use the shell

$ direc=${PWD##*/}
