Pattern Matching in Bash

[bdw238]

Hello,


Can someone advise me how to pattern match like the following bit of perl code in BASH

$message="There has been an error detected";
$pattern="error";
if ($message =~ m/$pattern/i) {
print "Found error\n";
} elsif {

# Do nothing

}

for a start:
man grep
man bash

e.g. your example:

message="There has been an error detected"
pattern="error"
echo $message | grep -q $pattern && echo "Found error"

hope this helps

case $message in *$pattern*) print "Found error\n";; esac

Hope This Helps, PH.

Or:

[tt]if [[ $message = *$pattern* ]] ; then echo "Found error" ; fi[/tt]
