Hey Guys,
I can not find the corrent syntax for what I am trying to acheive with a
while loop. Having said that I'm not exactly sure what you would call it so
I have been googling with no success probably for that reason.
I am just working with some sub directories except there is one I don't want
to use so I have a while loop like the following; if we stubmle into the sub
directory I wish to leave alone then there is an IF statement and I have
used the break command which is wrong, I don't want to end this whole loop I
just want to skip onto the next increment of the loop as it were skipping
this sub directory. Break is the wrong command but what should it be? Sorry
I can't be any clearer but I don't know exactly what you would call this
(which is why I am having no success finding it for my self!)
#!/bin/bash
find ./ -maxdepth 1 -type d | while read FOLDER
do
if [ $FOLDER == "./not_this_folder_oh_no!" ]; then
break
fi
<otherwise do some magic here>
done
Many thanks for your time and input.
Regards,
James ;)

"continue" is treated as a reloop operator; and you should quote
strings.

Thanks guys the "continue" command was what I was looking for. Also to those who pointed out the lack of quotation marks around the string, they are on my original script but somehow vanished during the copy and paste operation between my shell window and browser...werid?!?! Still If I hadn't of had those then you would of corrected me so thanks for that! Nice work listee's ;) -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT/MU/U dpu s: a--> C++>$ U+> L++> B-> P+> E?> W+++>$ N K W++ O M++>$ V- PS+++ PE++ Y+ PGP t 5 X+ R- tv+ b+> DI D+++ G+ e(+++++) h--(++) r++ z++ ------END GEEK CODE BLOCK------ -------------- next part -------------- An HTML attachment was scrubbed...

I'm just really currious.... JohnStanley
