Shell tricks (1)
Posted on | December 4, 2008 |
Some shell tricks, most of them interesting for deploying and handling your files:
find files recently modified (say in the last 2 days, -mtime 1):
1 | find . -type f -daystart -mtime 1 |
synchronize an entire directory to a remote server (overwrites everything, remote server has to have rsync installed too):
1 | rsync -avzpog yourdir you@remotebox:/remotedir/ |
other way around:
1 | rsync -avzpog you@remotebox:/remotedir/* yourdir/ |
build a listing of md5 checksums usefull for controlling the integrity of your files later:
1 | find ./yourdir/ -type f -exec md5sum {} \; > checksumlisting.lst |
use the generated list to check your files’ integrity:
1 | md5sum -c checksumlisting.lst | grep -i failed |
remove SVN directories from your tree of files:
1 | find ./ -name '*svn*' -exec rm -rf {} \; |
likewise for CVS directories:
1 | find ./ -name '*cvs*' -exec rm -rf {} \; |
if you messed up your console because you paged (more, less, head, tail) a binary file, reset your console display:
1 | reset |

Hi there!
I think this little collection is pretty useful.
Just a little comment: the -a switch for rsync implies the -pog, so you have to use the -a only (much easier to remember -avz only:). (And note that -a does not preserve hardlinks, so if you need to, use -H).

You are right,
-avz stands for: archive mode (symbolic links, devices, attributes, permissions and ownerships are preserved), verbose and (zlib) compressed.
-pog stands for: preserve permissions, owner and group which is obviously included in the archive mode mentioned above.
Don’t know why I remember it as -avzpog and why I started doing it like that instead of -avz. Note to self: use -avz.
cheers
