Running old Linux apps on new Distros

I have a number of customers running older Linux apps. Sometimes they have source for the app, sometimes they don't. Sometimes the original app vendor still exists and is willing to be helpful, sometimes they are out of business or uninterested in the old app because they want to sell something newer

Some UNIX tools I love  
- Without the clean design and power of UNIX OS, there could not have been the ecosystem and the atmosphere for programs that do great things. -

Digiboard Port Server changes tty device permissions  
- Earlier this week, one of those customers called with a problem of changing perms on his /dev/tty* devices. He needs them set with write permission (666), but some were seemingly randomly resetting to 600. -

Mplayer on UNIX and VLC on Windows   2011/10/19 anonymous
- Mplayer for Unix/Linux media playing. Both play multimedia files - both audio and video. But the approach taken towards solving this problem is quite different. -

Network Troubleshooting   2010/03/16 AndrewSmallshaw
- As it turned out, the problem was very physical: a light fixture had fallen down and loosened some connections to a long forgotten ethernet switch. -

What does a leading colon (:) mean in a script?  
- Bash and sh use colons as a separator ($PATH, for example), as a modifier (${n:="foo"}) and as a null operator ("while :"). -

Hylafax on Centos Scripts  
- Aside from transferring user accounts, printers, and so on, my work was just to convert Vsifax scripts to Hylafax. Those scripts were called by the application program to do such things as fax a Purchase Order to a vendor. The programming is simple enough: you find and extract the fax number and pass that all off to Hylafax. For purposes of logging and error control, we also wanted to identify the vendor name, which required adding that name to the logs that Hylafax keeps or maintaining a separate index of names to faxes queued. -

Unix and Linux startup scripts, Part 1  
- In the beginning, there was "init". If you had a Unix system, you had "init" and it was almost certainly process id 1. -

Unix and Linux startup scripts, Part 2   2009/12/11 TonyLawrence
- The rc.d system is used on NetBSD, FreeBSD and DragonFly (and possibly a few other systems) to launch daemon processes when the system goes multiuser. -

Unix and Linux startup scripts, Part 3  
- We have looked at both System V and BSD methods; until fairly recently that would hav e been the end of the discussion. -

Using color in shell scripts (Linux, Mac OS X)   2010/01/03 BigDumbDInosaur
- Color is tricky. Displays can be bad at it, people can be color blind... using colors can make text hard to read - I don't like using color in scripts. -

Sort -u vs. uniq  
- Don't tie yourself in pipeline knots with either of them; learn to use each of them appropriately and your scripts will be easier. -

Awk vs. Perl   2012/08/15 TonyLawrence
- Sure, I used to use awk. When I used it, you weren't likely to find Perl onmost Unix systems, so for a lot of text mangling, awk was at least easier than writing in C or anything else. It did the job, and you'd get used to its quirks. -

Hylafax 6 on Centos 5   2010/01/26 bubba
- I'm doing another SCO to Linux conversion and this one used Vsifax. That's hardly a show stopper, but this customer wanted to use Centos and Vsifax says they don't currently support using Centos. So we tried Hylafax. -

Prevent deletion or moving of files  
- You need to let users create files in a common directory, but you don't want them to be able to delete other's files. Or you've put certain files, directories or symlinks into a user's home directory and don't want them to be able to mess with any of those. What can you do? -

Plenty of space here  
- Like many people, my customer doesn't understand spaces in command lines. Unlike most, he's not one to leave spaces out - no, he's more likely to insert gratuitous spaces where none are wanted. -

Follow the bouncing dependencies  
- Now, given that I installed RHEL 5.3 from rpms, and did notcompile my own kernel, I figured that I would be missing some packages,but it turned into a major pain. -
