Let's lose all the surplus Shell syntax, remove, move, or correct many quote characaters, and just execute the command.
There is an issue with $TMPDIR because the value can only come from the login script. Let's assume that it has a value, otherwise every line mentioning $TMPDIR will fail.
I have no idea what is in /usr/atria/bin/cleartool but there is no possible way that a called process executed in this manner can change the environment of the calling process.
Assuming that /usr/atria/bin/cleartool is a Shell Script, it would need to execute in the current Shell environment if it was to change the current Shell environment.
Perhaps:
i.e dot-space-dot-slash-scriptname

mktemp
mktemp(1) General Commands Manual mktemp(1)Name
mktemp - make a name for a temporary file
Syntax
mktemp [ -c ] [ -d directory_name ] [ -p prefix ]
Description
The command makes a name for the pathname of a temporary file and writes that name to standard output. The name will not duplicate that of
an existing file. The command does not create a new file. The file named must actually be created before can generate a new filename.
Subsequent calls to will only generate a new file name if all previously generated file names have been created by the user and still
exist. Error messages are written to standard error.
The directory_name generated by is the concatenation of a directory name, a slash (/), a file prefix, a dot (.), a four digit number and a
unique character.
The directory name is chosen as follows:
(1) If the -d option is specified, directory_name is used.
(2) Otherwise, if the TMPDIR environment variable is set and a string that would yield a unique name can be obtained using the value of
that variable as a directory name, this value is used.
(3) Otherwise, is used.
The prefix is chosen as follows:
(1) If the -p option is specified, prefix is used.
(2) Otherwise, if the LOGNAME environment variable is set, it is used as the prefix.
(3) Otherwise, the user's login name is used.
Options-c Causes to attempt to create a regular file using the generated (or created) name string. If file creation is successful, a zero
length file is created with access permissions derived from the process's file mode creation mask, see No attempt is made to
create a file if the length of the generated (or created) name string exceeds 1023 characters. It is the user's responsibility
to remove files created by use of this option.
-d directory_name
Causes directory_name to be used as the directory portion of the pathname. In this case, directory_name is used instead of
TMPDIR and
-p prefix Causes the string prefix to be used as the file's prefix. It is used instead of LOGNAM and the user's login name. If the pre-
fix is longer the 249 characters, it will be silently truncated to that length before the concatenation of the suffix.
Environmental Variables
LOGNAME When the -p prefix option is not specified, the value of this variable is used as the prefix of the filename, if it exists.
TMPDIR When the -d directory_name option is not specified, the value of this variable is used instead of
Restrictions
If the user does not have write permission in the directory specified, and error message is reported and is used in its place. The entire
path name can not exceed 1023 characters, and the temporary file name can not exceed 255 characters. If the generated file name is too long
it is truncated to fit before the suffix is added.
