I said bash in the subject line
GNU bash, version 4.3.48(1)-release (i686-pc-linux-gnu)
LinuxMint 18.3 KDE 5.5.x
I wish to export the value of a variable (a date in MMDDYYHHMM.SS format; in the script: tdate or TDATE) set in a terminal shell to a script that will change the modification date of a file (referred to by the value of another variable, here picc) without my having to type in the relevant command. I have my laptop on an ordinary desk (in fact it has an Ethan Allen stamp on the inside of the drawer). My laptop has a 17" screen, and on the only chair I have for the desk, the armrests are too high for me to slide them under it. This makes it difficult for me to reach the laptop's keyboard, so I am using an ordinary desktop keyboard, set at an angle with the bottom resting on a ridge inside the front of the drawer. Therefore, I have to type "uphill," as I call it, an unconventional ngle in my experience, for typing. And since my typing is not the sort as taught in high school or business schools, I try to get away with doing as little of it as possible.
But enough of all that. I went about that explanation so you would know that, besides a script that isn't doing what I'd like, I have other challenges to contend with. No one on linuxquestions knows about them
It was indeed unfair of me not to put my OS, shell version and hardware in my signature on this forum. I will do so as soon as I finish this post.

I'm getting to grips with this concept of the umask.

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
