bash script gets stuck after sed
0
I have this bash script in CentOS 7 that creates users using a text document as input, the text document has 3 fields separated by colons; username:full name:email
The problem is that the script runs but it never finishes and according to the bash -x debug, it gets at least as far as the sed command but goes no further. The syntax used to run the script is script-name argument(input-file)
Here is the script in question:
#!/bin/bash
if [ $USER != "root" ]
then
echo "Note: You are required to run this program as root."
exit 1
fi
if [ "$#" -eq 0 ] # if no arguments after command
then
echo "You must enter an argument" >&2
echo "USAGE: $0 [-i {input-path}]" >&2
exit 2
fi
outputFlag="n"
while getopts i: name
do
case $name in
i) inputFile=$OPTARG ;;
:) echo "Error: You need text after options requiring text"
exit 1 ;;
?) echo "Error: Incorrect option"
exit 1 ;;
esac
done
if [ ! -f $inputFile ]
then
echo "The file pathname "$inputFile" is empty or does not exist" >&2
exit 2
fi
set $(sed 's/ /+/g' $inputFile) # temporarily convert spaces to + for storing lines as positional parameters
for x
do
userPassWd=$(date | md5sum | cut -d" " -f1)
useradd -m -c "$(echo $x | cut -d":" -f2 | sed 's/+/ /g')" -p $userPassWd $(echo $x | cut -d":" -f1)
mail -s "Server Account Information" $(echo $x | cut -d":" -f3) <<+
Here is your server account information:
servername: placeholder.servername.on.ca
username: $(echo $x | cut -d":" -f1)
password: $userPassWd
Regards,
IT Department
+
done
echo -e "nnAccounts have been creatednn"
exit 0
Here is are contents of the input file:
msaul:Murray Edward Saul:msaul@placeholder.on.ca
dward:David Ward:dward@placeholder.on.ca
eweaver:Evan Weaver:eweaver@placeholder.on.ca
sapted:Scott Apted:sapted@placeholder.on.ca
