small scripts doing small things
This is a collection of short scripts (shell, perl and python), some of them being oneliners (they could be shell aliases), some others doing little bit more complicated things that could be hard to remember.
These are my favorites, in order of preference:
-
nocomment
For sysadmin tasks, this is helpful to display only the very few lines that configure a service or a program without the comments nor the blank lines. Some services or applications ship their own facilities to dump their configuration (and check it, by the way):apt,postfix,bind9, and so on. But some other don't. Examples:nocomment /etc/ssh/sshd_config nocomment /etc/dhcp/dhclient.conf nocomment -r /etc/dnsmasq.d -
gpg-smartcard-reset-factory
If you plan to write somethihg to automate creation and storage of a GPG private keyring on a g10code GnuPG compatible smartcard, this piece of code may be of help. This it not mine, it comes from Werner Koch on gnupg mailling list.
