I have been trying to execute the below command by changing directory and then copying contents of one directory to another by doing some file name manipulations in between. However this isnt working since as soon as the statement completes it goes back to the original folder. Can someone help in telling me how to change a directory in a script so I can execute subsequent steps within it using and modifying a variable through the steps.
This works fine from command line, however gives bad substitution error from the script because of the issue explained above
Code:
for file in /ABC/DEF/*.done; do file="${file%.*}"; file="${file##*.}"; cp "${file:0:31}"*.* /ABC/EDG/; done
Basically check for all files with name like CAT_TURNAROUND_201811120_075221_3.done in the folder ABC/DEF/*.done, then get all the files starting with just this part CAT_TURNAROUND_201811120_075221from this directory/ABC/DEF/ copied to /ABC/EDG/
Will really appreciate a solution. I have been trying to figure this out and checked various forums and tried alias, function etc. But it isn't working.

mren
mren(1) General Commands Manual mren(1)NAME
mren - mtools utility to rename an existing DOS file
SYNOPSIS
mren [-v] sourcefile targetfile
OPTIONS
Specifies verbose mode. The new file name is displayed if the name supplied is invalid.
DESCRIPTION
The mren command renames an existing file on a DOS file system. You can also use the mren command to rename directories. Reasonable care
is taken to create a valid DOS file name. If an invalid DOS targetname is specified, the mren command changes the name and, if the -v
option is specified, prompts the user to accept or reject the new name.
The path component of the targetfile argument, if supplied, is ignored. That is, you cannot use the mren command to move a file from one
subdirectory to another.
DOS subdirectory names that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose
file names in quotes to protect them from the shell.
The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:.
Not all UNIX file names are supported in the DOS world. The mren command may have to change UNIX names to fit the DOS file name conven-
tions. The following table shows some examples of file name conversions:
-----------------------------------------------
UNIX name DOS name Reason for the change
-----------------------------------------------
thisisatest THISISAT file name too long
file.stuff FILE.STU extension too long
prn.txt XRN.TXT PRN is a device name
.abc X.ABC null file name
hot+cold HOTXCOLD illegal character
-----------------------------------------------
RESTRICTIONS
You cannot use the mren command to move a file from one subdirectory to another.
EXIT STATUS
The following exit values are returned: Success. Failure.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of mren: If set, this variable names the file that contains the name of the cur-
rent mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used.
FILES
Contains the name of the current mtools working directory as established by the mcd command. If this file does not exist, the default
mtools working directory is A:. Executable file
