why one linux command is working inside conatiner but not in entrpoint.sh - linux

Question

I am using ubuntu 16.04 OS as VM.
While creating container, i have some commands in entrpoint.sh which is not working or behaving as expected but the same command is working when i am manually running inside the container, to be precise below is my simple linux cp command which recursively copy from source to destination and also unzip command.
In my entrypoint.sh I have three commands :
cd /tmp/localization/Tpae7610
unzip \*.zip
cp -r /tmp/localization/Tpae7610/* /home/db2inst1/maximo/
Last two commands are not working when container starts, when I say it's not working it means it is not giving any error but not copying the source contents to destinations as expected also it is not unzipping the .zip files
NOTE: But same command is working as expected when i manually run inside the container.

Answer 1

Either the files under the directory /tmp/localization/Tpae7610/ are not having permissions.
Try the command cp -v ( verbose will show the file copied)
Comment the rm -rf localization in the script. Then debug the script.
