Command Dump – One line method to find errors in a large list of bind zone files

I have found need to go through a large list of bind zone files and find any that have errors.

This loop helps me identify them:

for a in `ls db.*.*|grep -v db.local.`; do named-checkzone localhost $a 2>&1 >/tmp/tmp; if [ "$?" != "0" ]; then echo "ERROR ON:$a"; cat /tmp/tmp; fi; done|more

• ls db.*.*|grep -v db.local.` – list each file that you would like to check (I listed all files with db.*.* and excluded any of them that started with db.local.)
• named-checkzone localhost $a 2>&1 >/tmp/tmp – run the check and save the results to a temp file
• if [ “$?” != “0” ]; then echo “ERROR ON:$a”; cat /tmp/tmp; fi; – if the command fails then print out the file name and the results
