Re: Quoting error: unexpected EOF while looking for matching `''

These test is made with the latest version of parallel.

This is from host:castor:

I dont have access to host=sko which has bash 4.1.5 rigt now. I'll try that later - also as another user.

So is it correctly understood that everything works as expected in bash 4.0.35?

Is it correctly understood that when running under bash 4.1.5 you get:

$ ls NEWS | parallel -q grep "'"

sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file

I have just tested bash-4.1.5(1)-release and I get the following
outout (which is what I would expect):

$ bash --version
GNU bash, version 4.1.5(1)-release (i486-pc-linux-gnu)

$ ls NEWS | parallel -q grep "'"
 sem 'sleep 2; echo foo'; sem 'sleep 1; echo bar'; sem --wait
 sem -j2 'sleep 2; echo foo'; sem -j2 'sleep 1; echo bar'; sem --wait
 cat tab_sep_table | parallel --colsep '\t' echo col1 {1} col2 {2}
* --sshloginfile '..' means use ~/.parallel/sshloginfile

So on my system bash 4.1.5 works as expected, too. My guess is that
your bash 4.1.5 installation does something unexpected. Maybe you have
some non-standard variables/options set?
