Linux 命令在 bash 中不起作用

Question

I have a bash script called AddUsers.sh. The script should take a line like this:

john.mccarthy@caltech.edu;1927/09/04;sudo,visitor;/visitorData

and return variables like this:

name=john
surname=mccarthy
bdate=1927/09/04    
uname=mccjoh
pass=1927
groups(array)=sudo, visitor
folder=/visitorData

When I run the script and give it the required text file, it is tellilng me that 'groupadd' 'chgrp' 'chmod' and 'chage' are all errors. Is anyone able to tell me why / give me any feedback?

Thanks in advance for any help.

#check for file
while [ ! -f  $file ]

    #ask user for filename
    echo What is the filename?

    #reading input as file name

    if [ ! -f $file ]
        then
            echo "File not found!"
        else

    fi

        then

you could use commands in scripts with full path address. and you can extract their full path address by "which" command. for example instead of using "chmod" you could use "/bin/chmod" type this to find full path: $which chmod
