In this example, we can store the names of two-person in a log file.

First, create a log file named ” Log.txt ” by the following command

$ touch Log.txt

Note: ” Log.txt ” will store the output.

Now, create a bash script file by the following command

$ touch Name.sh

Note: ” Name.sh ” It is a bash script file that will take two names from the user and store it into ” Log.txt “

Now, open ” Name.sh ” in a text editor

$ nano Name.sh

Now write the following bash script in ” Name.sh ”

#!/bin/bash
echo "Enter First Person Name : "

# It will take input from user i.e.
# First Person Name
read FName

# It store First Person Name in Log.txt
echo "First Person Name : $FName">Log.txt
echo
echo "Enter Second Person Name : "

# It will take input from user i.e. 
# Second Person Name
read SName

# It append Second Person Name in Log.txt
echo "Second Person Name : $SName">>Log.txt

Note: Here, ‘ > ‘ it will create a new file with a specified name if the file does not exist and it will use to overwrite the data stored in the file ( i.e. ” Log.txt “). And ‘ >> ‘ it will create a new file with a specified name if the file does not exist and it will append the output data in the file ( i.e. ” Log.txt ” )

Now save and run ” Name.sh ” by the following command

$ chmod +x ./Name.sh
$ ./Name.sh

As it is shown in the above picture that we take two inputs ” Sahil ” and ” Rakesh “. The output name will store in ” Log.txt “.
