- bash
- "Inline comment"... try...
echo Hello $(# cruel) world
- ":" and "/" are valid in function names.
Try...
/etc/hosts() { echo 'smile!' ; } ; /etc/hosts
Why not define a function to manage /etc/hosts this way?
Maybe like...
/etc/hosts add 10.1.2.3 newhost.in.my.net
- debian, package bash
- When a feature of a program or package is disabled by the maintainer, the manpage should reflect it. Look for /dev/tcp/host/port in bash's manpage and try to use bash's networking features.
- filesystem, links
- Dear developers and packagers: Please use relative links.
- init scripts
- Some initscripts have additional args, e.g. status. Why not use this way to add administration functions? Why not introduce a service like /etc/init.d/static-hosts-table with nops for start, stop, reload but functions like add, del, list, save, ...? Same for /etc/ethers, /etc/securetty, ...?
- python
- A commandline calculator for calculations too complicated for bash's
echo $((expression))
capabilities (e.g. when floats are needed):
python -c 'import math ; print expression'
where the import is not needed for simple things.
- windows
- windows vs linux
Sometimes I wish the linux world would not be so divergent. But sometimes I think it is nice to have thousands of choices/alternatives/parameters...
Windows is like "eat or die". But what if I forget to eat while trying to find the best set of choices and parameters for the same problem on linux? I'm starving too...
I'm a linux fan since kernel-0.11 and sure I am a settled and true fan of free software, but that does not mean that I suggest linux to everybody I meet. There are some cases in which I point someone into the windowsish direction and I can live with it...
