Shell Programming and Scripting

Importing images from a camera (or two).
I sort by date (1901 this month).

Currently (failing)

Code:

if [[ -d $pana ]]
then
 echo "Found Panasonic G9X"
      #echo "List files on camera"
      #ls ${pana}/*
       . chxdir.sh ${photos}/$mn

I want to change directory to a fixed base ($photos)/$mn obtained from current year month.

How to get this to work please?
Must I call the script with . script or some such?
Frustrating!

Can you explain:
. chxdir.sh ${photos}/$mn ?
And tell us what shell you are using ( looks like bash...)

An attempt to change directory, with another script? Which failed,
And yes, using bash on fedora (though happy with zsh)

Not knowing the contents of ${photos}, $mn, or chxdir.sh, we cannot begin to guess. Try set -x to run with debug trace.

As a start, verify that all your variables are what you think they are with echo . chxdir.sh ${photos}/$mn And if you edited any of your scripts in Microsoft Notepad, that will have filled them with invisible carriage return characters which you must delete with tr -d '\r' < inputfile > outputfile for it to work. outputfile must be a different name than inputfile.

Otherwise, not knowing the contents of ${photos}, $mn, or chxdir.sh, I cannot begin to guess. My crystal ball is out of order.

Stripped test.

Code:

current directory = /a
target= /b
mn=`date  +%y%m`

I want to

Code:

cd to $tgt
cp /a/*.jpg to ./${mn}

I can't get my head round the shell script working directory vs current working directory
Hence the failed chxdir script

a synonym for a point . is "source".
This means not the execution of the script but the insertion of the contents of this file into the current location.
This command has no second parameter
