Problem:

How to change a string on several files by bash without opening one by one.

Solution:

for i in $(find . -type f); do sed ’s/find/replace/g’ $i > $i-tmp; mv $i $i-backup; mv $i-tmp $i; done

Yes, it’s just a copy paste from the source, i don’t have time to explain each command.

When migrating to a new server you will forget to:

- Check php session folder pemissions (/var/lib/php/session/ this folder must be writable)

- Do a DNS reverse setup, and will only notice when emails start to bounce.

- To configure dovecot you need to enable the protocols AND make sure it’s listening to internet as well (webmin configuration is ambiguous and bugged, you should edit the conf file manually)

- To add ALL old users BEFORE doing the file copy

- To add a trailing slash (/) when doing rsync file copy, which will generate /home/user/home/user/ instead of /home/user/

- To check server’s firewall before starting apache and wondering why nothing is working.

- When setting up a new nameserver, you always tend to ignore “.org, .net, .com only” which might cause lots of headaches later, when you realize that ns will not work, after changing 100 domains.
