I have a list of filenames that I want created - they must be created via a certain naming convention due to the software I'm using. Once they are created I have another file that will be used to populate them with data. So far this is what I have:
Code:
#For each line in text file "foo_txt" create a file with that name:
for i in $(cat create/foo_txt); do
touch create/foodir/$i;
#For each line in text file "bar_txt" store the line of text in each file created by foo_txt:
for i in $(cat create/bar_txt); do echo $i >> create/foodir/<each_file_from_foo_txt>; done
For example, foo_txt would contain the following:
Code:
file_a
file_b
file_c
file_d
And four files would be created. bar_txt would contain the following:
Some of the lines from bar_txt would be appended to a file created from foo_txt which is why I'm using the ">>", and that's why the files from foo_txt would contain more than 1 line from bar_txt - whatever filename is listed in foo_txt at the time each line of bar_txt is read.

wall
WALL(1) User Commands WALL(1)NAME
wall - write a message to all users
SYNOPSIS
wall [-n] [-t timeout] [-g group] [message | file]
DESCRIPTION
wall displays a message, or the contents of a file, or otherwise its standard input, on the terminals of all currently logged in users.
The command will wrap lines that are longer than 79 characters. Short lines are whitespace padded to have 79 characters. The command will
always put a carriage return and new line at the end of each line.
Only the superuser can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies
messages.
Reading from a file is refused when the invoker is not superuser and the program is set-user-ID or set-group-ID.
OPTIONS -n, --nobanner
Suppress the banner.
-t, --timeout timeout
Abandon the write attempt to the terminals after timeout seconds. This timeout must be a positive integer. The default value is
300 seconds, which is a legacy from the time when people ran terminals over modem lines.
-g, --group group
Limit printing message to members of group defined as a group argument. The argument can be group name or GID.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
NOTES
Some sessions, such as wdm, that have in the beginning of utmp(5) ut_type data a ':' character will not get the message from wall. This is
done to avoid write errors.
SEE ALSO mesg(1), talk(1), write(1), shutdown(8)HISTORY
A wall command appeared in Version 7 AT&T UNIX.
AVAILABILITY
The wall command is part of the util-linux package and is available from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils/util-
linux/>.
