Synopsis:
$sar([i][g][r]/<search>/<replace>/<text>)
Technical:
This function searches for the given search string in the given text, and
replaces if with the replacement text, if a match is found. The field
delimiter may be any character; the first character found that is not a
'g' or 'r' is used.
Practical:
This is the general purpose search-and-replace function. It allows you
to look for any arbitrary text substring in any text string, and replace
it with another arbitrary substring. Any of the strings may consist of
variables to expand at runtime.
Returns:
resultant string
Options:
i do case-insensitive searches
g replace all matches, not just the first
r assume text is a variable name; assign return value to variable
Examples:
@ foo = [foobarblah]
$sar(/oo/ee/booyamon) returns "beeyamon"
$sar(/oo/ee/foofoo) returns "feefoo"
$sar(g/oo/ee/foofoo) returns "feefee"
$sar(r/oo/ee/foo) returns and sets $foo to "feebarblah"
