Folk IT – and other articles about dealing with the business

An interesting article for those who have the time.

Its about business coming up with solutions to IT probs – ‘Folk IT’ – since they learn the IT terminology when things go wrong, they may as well contribute to the solution right?  right?  wrong….

Taken from the Thoughworkers article list here.  Something I’d love to read more of when I have the time.

Shared Libraries on Linux

Fun = figuring out shared library deps on linux.  Not…

This useful article (Program Library-HOWTO) talks about how lib files are discovered and what you can do to force them to be found.

LD_LIBRARY_PATH which I’ve seen many times before, allows you to specify a library ahead of others so you can do

LD_LIBRARY_PATH=.:/my/better/lib.so:$LD_LIBRARY_PATH

If you want to see which libraries a process is using then do

ldd /path/to/your/process

There is still a magic to how those libraries then link off and refer to others but this is considerably more than I knew 24 hours ago 🙂

Multiline Bash

This is so simple, yet so easily forgotten

$ echo ‘this is a test of the emergency
> backslash multiline
> prompt system.
> When will it end, I dont know for sure
> how about if i close the string’

this is a test of the emergency
backslash multiline
prompt system.
When will it end, I dont know for sure
how about if i close the string

So in your sh scripts, can end each line with a sole backslash, for your command to wrap to the next line (and make your scripts easier to read).

Apparently, env variable PS2 will define what the > prompt appears as.
