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.

SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-c COMMAND] [-e] [-f] [-q] [-t] [file]
DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-c COMMAND
Run the COMMAND rather than an interactive shell. This makes it easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-e Return the exit code of the child process. Uses the same format as bash termination on signal termination exit code is 128+n.
-f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
vise real-time what is being done using `cat foo'.
-q Be quiet.
-t Output timing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
to replay typescripts with realistic typing and output delays.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism), scriptreplay(1).
HISTORY
The script command appeared in 3.0BSD.
BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
AVAILABILITY
The script command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
