Re: quote interpretation via vars without eval

[Alex fxmbsw7 Ratchev]

right it wasnt the output however it prints it as ? excepts | cat etc yea
.. i cannot agree anymore to ls being useless
especially after looking at its man page

to detail the find \ ls issue
i build a multiline prompt, one line recent dirs one line recent files
that means recent... modification time, i tried find, i tried stat, ls is
best suited for this ( its already working ) - pasted [attached] already

by recents mean parsing finds or stats output, sort -n, awk .. and the
problem was the filename contained ?, even worse if it was empty like non
\1 or \001, or stat didnt have subsecond mod time showment ( ? )

im quite happy with the ls output, excepts \001 has to be shortened and the
'' cut away

btw greycat if you didnt watch it was command ls
--quoting-style=shell-escape -cF ( | awk .. )
