You
help me create a bash script where the command is /usr/local/directadmin/directadmin admin-backup –destination=/home/admin/admin_backups –user=testuser1 –user=testuser2 –user=testuser3 testuser1 testuser2 testuser3 lines are read from an external text file each on its own line

Here is a bash script that reads the usernames from an external text file and runs the command for each user:
bash#!/bin/bash
# Set the input file and command
INPUT_FILE="users.txt"
COMMAND="/usr/local/directadmin/directadmin admin-backup --destination=/home/admin/admin_backups"
# Read the users from the file
while IFS= read -r username; do
# Run the command for each user
${COMMAND} --user=${username}
done < "${INPUT_FILE}"
Let me explain what’s going on:
- The first line,
#!/bin/bash
, specifies the interpreter that should be used to run the script.
- We set the input file (
users.txt
) and command (COMMAND
variable) at the top of the script.
- The
while
loop reads each line from the input file using IFS= read -r username
. The -r
option tells read
to treat backslashes as literal characters, rather than interpreting them as escape sequences. This is important if your usernames contain special characters.
- Inside the loop, we run the command for each user by concatenating the
COMMAND
variable with the --user=
parameter and the current username.
To use this script, simply create a file called users.txt
in the same directory as the script, with one username per line:
texttestuser1
testuser2
testuser3
Then, make the script executable by running chmod +x scriptname.sh
, and then run it by typing ./scriptname.sh
.
Note: Make sure to replace users.txt
with the actual path to your input file if it’s located elsewhere.
