We have a set of Oracle installation (Linux) scripts that are stored on a Windows server. When needed, Dave "the NumbThumb" zips them up and sends them to us to play with. We are well used to adjusting access permissions, in fact we have a little script that looks after attributes of files that arrive from the dark side.
Today I've realised that mixing command line and GUI file manager is no good. Martin opened a GUI file manager and tried to run one of the scripts by double-clicking on the icon. Instead of running, an editor was opened. We quickly realised that the 'x' permission was missing. So I dropped into the command line, and did a quick:
# chmod +x *.sh
Run ls –l to confirm the change – OK. Martin tries to run the script again, but no difference: script didn't execute, but the editor opened again. Conclusion: if you have a GUI screen showing file icons, and change file attributes from the command line, don't expect GUI to take any notice.
The whole experience proves the very old recommendation of working with UNIX : when working on any particular task it’s best to stick to either the command line or GUI, don't mix them!
