I find myself editing multiple files, sometimes with the same bits of information. My bash script, a changelog, and a plist file (OS X). Once I realized this, I thought why not script part of this process (and so it begins). In any case, I've solved several of the tasks I've set forth for myself. My new update script will update version/revision numbers in all files, and add text to the top of my change log using a combination of bash, python, and now perl (I think I'm nerding out a bit). I know this is all overkill, I just wanted to see if I could do it.
So, with the command
Code:
./update.sh 1.8.8.8 "some text for a change log header" /some.plist
Well, maybe not stuck. It works fine. But, if I could somehow make this perl one-liner also wrap text at 80 columns and add a "#\t\t" at the start of each line (and make me a sandwich).... Is that just asking too much? Maybe I should cut down on the energy drinks.

Hi ,

Greetings!
Some of my files list hardware errors (we test electronic components), some have none. If the file name has no errors, I still want to display a message like "No error", else I display the error from the file itself.

sysprofile
SYSPROFILE(8) System Manager's Manual SYSPROFILE(8)NAME
sysprofile - modular centralized shell configuration
DESCRIPTION
sysprofile is a generic approach to configure shell settings in a modular and centralized way mostly aimed at avoiding work for lazy sysad-
mins. It has only been tested to work with the bash shell.
It basically consists of the small /etc/sysprofile shell script which invokes other small shell scripts having a .bash suffix which are
contained in the /etc/sysprofile.d/ directory. The system administrator can drop in any script he wants without any naming convention
other than that the scripts need to have a .bash suffix to enable automagic sourcing by /etc/sysprofile.
This mechanism is set up by inserting a small shell routine into /etc/profile for login shells and optionally into /etc/bashrc and/or
/etc/bash.bashrc for non-login shells from where the actual /etc/sysprofile script is invoked:
if [ -f /etc/sysprofile ]; then
. /etc/sysprofile
fi
For using "sysprofile" under X11, one can source it in a similar way from /etc/X11/Xsession or your X display manager's Xsession file to
provide the same shell environment as under the console in X11. See the example files in /usr/share/doc/sysprofile/ for illustration.
For usage of terminal emulators with a non-login bash shell under X11, take care to enable sysprofile via /etc/bash.bashrc. If not set
this way, your terminal emulators won't come up with the environment defined by the scripts in /etc/sysprofile.d/.
Users not wanting /etc/sysprofile to be sourced for their environment can easily disable it's automatic mechanism. It can be disabled by
simply creating an empty file called $HOME/.nosysprofile in the user's home directory using e.g. the touch(1) command.
Any single configuration file in /etc/sysprofile.d/ can be overridden by any user by creating a private $HOME/.sysprofile.d/ directory
which may contain a user's own version of any configuration file to be sourced instead of the system default. It's names have just to
match exactly the system's default /etc/sysprofile.d/ configuration files. Empty versions of these files contained in the $HOME/.syspro-
file.d/ directory automatically disable sourcing of the system wide version.
Naturally, users can add and include their own private script inventions to be automagically executed by /etc/sysprofile at login time.
OPTIONS
There are no options other than those dictated by shell conventions. Anything is defined within the configuration scripts themselves.
SEE ALSO
The README files and configuration examples contained in /etc/sysprofile.d/ and the manual pages bash(1), xdm(1x), xdm.options(5), and
wdm(1x). Recommended further reading is everything related with shell programming.
If you need a similar mechanism for executing code at logout time check out the related package syslogout(8) which is a very close compan-
ion to sysprofile.
BUGS
sysprofile in its current form is mainly restricted to bash(1) syntax. In fact it is actually a rather embarrassing quick and dirty hack
than anything else - but it works. It serves the practical need to enable a centralized bash configuration until something better
becomes available. Your constructive criticism in making this into something better" is very welcome. Before i forget to mention it: we
take patches... ;-)
