Following up my own post, sorry, but I thought the above incomplete after
a bit more testing:
It seems like it's OK to "" the left side of the comparison,
but not the regex which should be matched:
=============================================================================
[EMAIL PROTECTED]:~/make> if [[ "sploerp" =~ s.*rp ]] ; then echo yes ; fi
yes
=============================================================================
If the regex-pattern is ill-suited to be matched without somehow "enclosing" it,
round brackets seem to work fine (which is to be expected, but I thought
I'd mention it anyway...)
=============================================================================
[EMAIL PROTECTED]:~/make> if [[ "sploerp" =~ s[ ]*.*rp ]] ; then echo yes ; fi
bash: syntax error in conditional expression
bash: syntax error near `]*.*rp'
[EMAIL PROTECTED]:~/make> if [[ "sploerp" =~ (s[ ]*.*rp) ]] ; then echo yes ; fi
yes
=============================================================================
greets,
Jens
