In each line of file, I wish to check if word1 is a non-connected subset of any of the other words in the line. If yes, keep only the words that ward1 is a subset of. Else, remove the whole line.
Also, I want to remove the letters that word1 doesn't match with, except for "_+"

tail
TAIL(1) FSF TAIL(1)NAME
tail - output the last part of files
SYNOPSIS
tail [OPTION]... [FILE]...
DESCRIPTION
Print the last 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With
no FILE, or when FILE is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
--retry
keep trying to open a file even if it is inaccessible when tail starts or if it becomes inaccessible later -- useful only with -f
-c, --bytes=N
output the last N bytes
-f, --follow[={name|descriptor}]
output appended data as the file grows; -f, --follow, and --follow=descriptor are equivalent
-F same as --follow=name --retry
-n, --lines=N
output the last N lines, instead of the last 10
--max-unchanged-stats=N
with --follow=name, reopen a FILE which has not changed size after N (default 5) iterations to see if it has been unlinked or
renamed (this is the usual case of rotated log files)
--pid=PID
with -f, terminate after process ID, PID dies
-q, --quiet, --silent
never output headers giving file names
-s, --sleep-interval=S
with -f, sleep for approximately S seconds (default 1.0) between iterations.
-v, --verbose
always output headers giving file names
--help display this help and exit
--version
output version information and exit
If the first character of N (the number of bytes or lines) is a `+', print beginning with the Nth item from the start of each file, other-
wise, print the last N items in the file. N may have a multiplier suffix: b for 512, k for 1024, m for 1048576 (1 Meg).
With --follow (-f), tail defaults to following the file descriptor, which means that even if a tail'ed file is renamed, tail will continue
to track its end. This default behavior is not desirable when you really want to track the actual name of the file, not the file descrip-
tor (e.g., log rotation). Use --follow=name in that case. That causes tail to track the named file by reopening it periodically to see if
it has been removed and recreated by some other program.
