Useful scripts

[denise]

(Can you tell I've been coding lately? Like the last four posts here have been from me ...)

I was talking with rb this evening about useful scripts I have put together for my dreamhack -- some of which I came up with myself, and some of which I stole from other people, such as mark -- and figured it would be a good idea to post them and ask everybody else to post their own useful scripts!

(If you want to install these to your own 'hack, put them in ~/bin and then chmod +x filename to make them executable.)



1. sl -- syncs the live code (in ~/dw) to the code in cvs (~/dw/cvs/dw-{non}free)

#!/bin/bash $LJHOME/bin/cvsreport.pl -s -l


2. sc -- syncs the code in cvs (~/dw/cvs/dw-{non}free) to the code in live (~/dw), and cleans up any .orig or .rej files lying around from previous reversions or failed patch attempts. (Might produce a "rm: missing arguments" if there are none of those files.)

#!/bin/bash find -name *.orig -o -name *.rej | xargs rm $LJHOME/bin/cvsreport.pl -s -c

3. tidy -- cleans up any .orig or .rej files lying around. Will produce a "rm: missing argument" if there are none of these files.

#!/bin/bash find -name *.orig -o -name *.rej | xargs rm

4. dbu -- runs the database update commands. does NOT pull most recent code first -- use this when you've made styles changes or made changes to the db schema in order to see your changes reflected on the live site.

#!/bin/bash $LJHOME/bin/upgrading/update-db.pl -r -p --innodb && \ $LJHOME/bin/upgrading/update-db.pl -r --cluster=all --innodb && \ $LJHOME/bin/upgrading/texttool.pl load

5. bap: for Bounce APache. stops and starts apache (need to do this if you've changed any .pm files in order for your changes to be reflected on your 'hack -- if you're making changes and they aren't being reflected in the browser when you reload the page, and you're positive you're working in live and not in cvs, bounce the apache.) I totally stole the name from mark.

#!/bin/bash echo "Restarting apache ... BAP!" /usr/sbin/apache2ctl -f ~/apache/conf/httpd.conf -k stop sleep 5 /usr/sbin/apache2ctl -f ~/apache/conf/httpd.conf -k start

6. upgrade: does all the steps necessary to upgrade your 'hack to the most recent code. (don't run this if you have any changes in either your live or cvs directory -- it will error. pop your patches off the stack, or revert everything, and then run the upgrade commands.)

#!/bin/bash stop-apache && \ hg -R $LJHOME/cvs/dw-free qpop -a && \ hg -R $LJHOME/cvs/dw-nonfree qpop -a && \ $LJHOME/bin/cvsreport.pl -u && \ hg -R $LJHOME/cvs/dw-free qpush -a && \ hg -R $LJHOME/cvs/dw-nonfree qpush -a && \ $LJHOME/bin/cvsreport.pl -s -c && \ $LJHOME/bin/cvsreport.pl -s -c && \ $LJHOME/bin/upgrading/update-db.pl -r -p --innodb && \ $LJHOME/bin/upgrading/update-db.pl -r --cluster=all --innodb && \ $LJHOME/bin/upgrading/texttool.pl load && \ start-apache

So, what other useful scripts do you have?

If you want to suppress the rm error in 3:

#!/bin/sh
find -name \*.orig -o -name \*.rej -print0 | xargs -0r rm

This also still works correctly if you have a file in the current directory ending in .orig or .rej (by escaping the wildcards so that the shell doesn't try to expand them), and uses -print0 and -0 to xargs so that it properly handles filenames containing spaces.

This assumes GNU or GNU-compatible find and xargs, but that's a fairly safe bet at this point, I think, at least for those features.

Sweet, thank you!

* bash aliases work better for one-liners

* Mark totally ganked bap from LJ, lol. I do wonder how your ops restarts the web tier servers every release, though.

restart-webs from the admin box; sorry about the yawn-worthy name...
