I like your idea, because of its simplicity. Its main drawback is that, at least according to my manpage of test, it does not work with the -N file test operator (true if file exists and its access time is not newer than its modification time)
I just tried that out of curiosity and now realize I was slightly wrong.
In most shells, test is a builtin which supports all operators the shell does.
...so if your shell has it as a builtin you are set.
I definitely reccommend against injection rejection which leaves you wide open to things you don't know about and can react badly to valid things you still didn't expect. (What if a filename contains a literal backtick?) Better to not leave the door open in the first place and use something which doesn't allow for shell interpretation.

hi,
In bash,
$ bind -P | grep yank-last
yank-last-arg can be found on "\M-.", "\M-_".
this allows me to press ALT key and the period (.) to yank the last argument of
the previous command line into the current command line.
How can I get the same behavior in zsh ?
Thanks ... (0 Replies)

Inside a zsh function, I create a local array with local -a arrayname and a local associative array with local -A arrayname.
I also can create an array using set, like this:
set -A arrayname value1 value2 value3In this form, I can not explicitly declare that an array is associative or... (2 Replies)

test
TEST(1) General Commands Manual TEST(1)NAME
test, [ - test for a condition
SYNOPSIS
test expr
[ expr ]
OPTIONS
(none)
EXAMPLES
test -r file # See if file is readable
DESCRIPTION
Test checks to see if files exist, are readable, etc. and returns an exit status of zero if true and nonzero if false. The legal operators
are
-r file true if the file is readable
-w file true if the file is writable
-x file true if the file is executable
-f file true if the file is not a directory
-d file true if the file is a directory
-s file true if the file exists and has a size > 0
-t fd true if file descriptor fd (default 1) is a terminal
-z s true if the string s has zero length
-n s true if the string s has nonzero length
s1 = s2 true if the strings s1 and s2 are identical
s1 != s2 true if the strings s1 and s2 are different
m -eq m true if the integers m and n are numerically equal
The operators -gt, -ge, -ne, -le, and -lt may be used as well. These operands may be combined with -a (Boolean and), -o (Boolean or), !
(negation). The priority of -a is higher than that of -o. Parentheses are permitted, but must be escaped to keep the shell from trying to
interpret them.
