awk: Print the fifth column (a.k.a. field) in a space-separated file.

$ awk '{print $5}' ${filename}

try on your machine

This command uses the awk utility to extract the 5th field (column) from the contents of the file specified by ${filename}.

Here is a breakdown of the command:

awk: This is a command-line utility used for text processing and pattern matching in Unix and Linux environments.
'...': The command is enclosed in single quotes to ensure that any special characters or spaces within the command are treated literally.
{print $5}: This is the action to be performed by awk. It tells awk to print the value of the 5th field from each input line.
${filename}: This is a placeholder representing the actual filename you would provide as an argument to the awk command when executing it. For example, if the actual filename is data.txt, you would replace ${filename} with data.txt.

When the command is executed, awk reads the contents of the file ${filename} line by line. It separates each line into fields based on the specified field separator (typically whitespace). It then prints the value of the 5th field from each line.
