much about $1 vs “$1″ and using $() vs “. Nowadays bashisms are probably OK but in my time if you worked with Solaris you’d better stick to the original Bourne sh and keep in mind the awk/nawk/gawk thing. But the way I understand some rumors it’s not the Bourne shell one needs to learn but how to tie the tie and the subtle shades of blue. JCL, too. As for shell scripting I’d say a C compiler would be a worthy challenge. The code doesn’t have to be fast,just basic executable generation. I’ve always said I could do one but noone called me so far. Commands outside of builtins are allowed up to about gawk level, but no perl, please. Pretty much anyone could do a C compiler with perl 5.6 and above.

test “” = $NOSUCH
bash: test: : unary operator expected

which I guess is why I tend to always quote as well :p

I definitely should not have shell on my resume.

$ if [ -z -o -z ]; then echo xx; fi
xx

I think the if line will be a syntax error if the strings are really empty (unset). I would double quote them.

Long time since I have seen that, long time
