rsync Permalink

Shell, rsync Added less than a year ago and last edited about a month ago

When I have 90% common files on my laptop and desktop, and I want to sync the remaining files without accidentally deleting anything, I run these commands:

$ rsync -pogz -urave ssh ~/localdir remote.computer:~/
$ rsync -pogz -urave ssh remote.computer:~/localdir ~/

Then, as you are sure you are now up-to-date on both machines, you can start deleting files on one, and then sync those deletions to the other with:

$ rsync --delete -pogz -urave ssh ~/localdir remote.computer:~/

Note:

rsync doesn't seem very good at moved files. It will try to copy the whole file across again if it has moved into another dir... check out the fuzzy option... and also this thread for further info.

Timezone Permalink

Shell, Linux Added less than a year ago

If you have a *nix box, you can set the timezone of the box by making /etc/localtime a symlink to the appropriate /usr/share/zoneinfo/ file.

But what if different people on your box have different timezones? Each user can manually set his own timezone simply by doing this:

$ export TZ=Australia/Hobart

... why not put that in your .bashrc?

utf8 in your Perl Permalink

Perl Added less than a year ago

Just by using the utf8 pragma in your Perl, you can do things like this:

use Modern::Perl;
use utf8;

my $天 = 'sky!';

say $天;

for my $否 (split(/ /, "no no NO no! NO!")) {
    say $否;
}

Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them.

Colours in your PAGER Permalink

Perl, Shell Added less than a year ago

Seeing escape codes when you run perldoc?

Set your $PAGER environment variable up correctly:

export PAGER="less -R"

zsh vared Permalink

zsh Added less than a year ago

vared:

zsh% blah="some very long thing here"
zsh% echo $blah
some very long thing here
zsh% vared blah
some very long thing here oh here is my edit
zsh% echo $blah
some very long thing here oh here is my edit

.. when you do a vared variablename, it will print the current value of the variable and puts the cursor at the end, waiting for you to edit the line. So if you need to edit your PATH, and want to add something new to the end - or change the last directory, vared makes it easy.

zsh magic-equals and double-star Permalink

zsh Added less than a year ago and last edited less than a year ago

The magic-equals:

bash$ ls `which perl`
/opt/local/bin/perl

zsh% ls =perl
/opt/local/bin/perl

The double-star:

zsh% ls proj/bin/tools/mysql_fix.pl # `mysql_fix.pl' is in our tree
proj/bin/tools/mysql_fix.pl

zsh% head -1 **/mysql_fix.pl # double-star knows where to find it!
#!/usr/bin/env perl

Funny Tweets Permalink

Comedy, Perl Added less than a year ago

... between two Perlers today:

chromatic:

Some days the jerks and bugs and workarounds and fame-chasing pundits make me want to leave technology as a profession.

Larry Wall:

If you do leave, you will find jerks and bugs and workarounds and fame-chasing pundits in most other professions too.

chromatic

At least real life hides its backwards compatibility misfeatures in DNA where I can't get at it.

Haha :-)
