Public bug reported:
I use (and have been using for 20 years or so) a path variable that looks like
PATH=".;./bin;~/bin;$PATH"; export PATH
This PATH should execute in priority: project specific commands (in the
working directory, or the bin
subdirectory of the working directory), my personal commands (in my $HOME/bin
folder) and then system commands.
The problem seems to be that when I start a shell in my home directory, it will
cache the location of commands in ~/bin
as if they were in ./bin and then will be unable to find them if I cd out of my
home directory.
For example, I have a personal command called SlideShow:
Here is a short example:
ralmond@Limu:~$ file ~/bin/SlideShow
/home/ralmond/bin/SlideShow: POSIX shell script, ASCII text executable
ralmond@Limu:~$ # Works fine if I execute it from home directory
ralmond@Limu:~$ SlideShow Pictures/
^C [Working as expected]
ralmond@Limu:~$ cd Pictures/
ralmond@Limu:~/Pictures$ #But if I change directory it does not work.
ralmond@Limu:~/Pictures$ SlideShow Pics
bash: ./bin/SlideShow: No such file or directory
ralmond@Limu:~/Pictures$ #If I start the shell in a directory other than home
it works
ralmond@Limu:~/Pictures$ bash
ralmond@Limu:~/Pictures$ SlideShow Pics
^C [Working as expected]
I suspect that it is some cache which is not properly getting reset.
Here are my system details:
