if echo $x | grep foo then ... fi

I feel that there should be - and most likely is - a better way to phrase...

Unless you assume a specific shell....
Sed 's/foo/bar/' <<< "foobie" grep 'this' <<< need it.
Fi
Where foo is a regular expression.
Fi
Consider using:
if [ $x =~ foo ] then ...
Be
Instead of:
if echo $x | grep foo then ...

Another option would be to use output....
If(true) { ?> Regular HTML Here <?php } else { ?> Regular HTML Here <?php }
You can break out of PHP at any time using the '?> it.
You can simply break out of PHP in the if/else statement .

If [[ $i=~200[78] ]] ; then echo "OK" else echo "not OK" fi
Hi,
Could it be you need quotes around need spaces around the operator =~
i="test" if [[ $i =~ "200[78]" ]]; then echo "OK" else echo.

Usually I use David Sky's "bouncing ball" effect plug-ins, but I've always been
disappointed when "extra" space is created due to wrong delay times being
entered. For instance, several seconds of silence.
To counteract this, I created this plug-in, which...

So....
So your expression means the same as the first three characters are not dev ( ^(?!dev) ) AND the first character is a full stop ( ^\ .
A negative passive group (lookahead) should do:
/^(?!dev).*\./Ui
Look-arounds do not “consume” any characters .

Element-(\d+)/i
That's a regular expression that would capture the numbers after the dash | elementID | | storeEval | '${elementID}'.replace("element-", "") | myID |
Now if I echo myID I get just the ID:
| echo | ${myID} | 12345 ....
