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.

--- I'm no Bash expert but is there a real good reason "pass" would not be used in place of continue? I'm just really currious....

Because pass is not a valid bash language construct, at least in 3.2.25.

Reverse the logic in the test and consolidate further
#!/bin/bash find ./ -maxdepth 1 -type d | while read FOLDER do if [ $FOLDER != "./not_this_folder_oh_no!" ]; then <do some magic here> fi done
Or exclude the directory in the find command itself
#!/bin/bash find ./ -maxdepth 1 -type d -wholename './not_this_folder' -prune -o - -print | while read FOLDER do <do some magic here> done
