I would like some help to find the regexp to test that a word does not contains anything than the character set of printable strings.
Especially the word should not contain a underscore.
Code:
echo "$word" | grep "([A-Za-z][0-9] \'\(\)+,-\.:=\?)+"
if [ $? -eq 0 ]
then
echo success
else
echo failed
fi

I'm not talking about the assembly instruction TAS, a better name could be check-and-set :) Anyway, is there a way to simplify the following
if ; then VAR="something"; fi
I have ~20 variables that should be test-and-set like this, and it really looks lame. (2 Replies)

echo
ECHO(1) BSD General Commands Manual ECHO(1)NAME
echo -- write arguments to the standard output
SYNOPSIS
echo [-n] [string ...]
DESCRIPTION
The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline ('
') character, to the
standard output.
The following option is available:
-n Do not print the trailing newline character. This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2
compatible systems. Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001
(``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup-
press the newline character.
Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does
not accept the -n option. Consult the builtin(1) manual page.
EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs.
SEE ALSO builtin(1), csh(1), printf(1), sh(1)STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
