I have a bash script I've been using in CentOS that no longer works in Fedora 14. The pertinent lines are: mac=`echo $2 | tr a-z A-Z` if [[ "$mac" =~ '[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]' ]]; then echo 'good' else echo 'Invalid MAC address' fi In CentOS or RHEL5 setting parameter 2 = 00:00:00:00:af:df works as expected, but not in Fedora. By adding -x to the first line of the script the output to the terminal in CentOS looks like this: ++ echo 00:00:00:00:af:df ++ tr a-z A-Z + mac=00:00:00:00:AF:DF + [[ 00:00:00:00:AF:DF =~ [0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F]:[0-9A-F][0-9A-F] ]] + echo good good In Fedora it looks like this: ++ echo 00:00:00:00:af:df ++ tr a-z A-Z + mac=00:00:00:00:AF:DF + [[ 00:00:00:00:AF:DF =~ \[0-9A-F]\[0-9A-F]:\[0-9A-F]\[0-9A-F]:\[0-9A-F]\[0-9A-F]:\[0-9A-F]\[0-9A-F]:\[0-9A-F]\[0-9A-F]:\[0-9A-F]\[0-9A-F] ]] + echo 'Invalid MAC address' Invalid MAC address Note the "\" before each "[" in the regular expression. Any ideas what is going on here? Is there a better forum to ask this question? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
