What Linux command makes `A B C` become `A C B`?
Jun 25, 2:06pm

To swap the positions of B and C in the string A B C using Linux commands, you can use the following approach with echo and awk:

bash
echo "A B C" | awk '{print $1, $3, $2}'

Explanation:

  • echo "A B C": Outputs the string A B C.
  • awk '{print $1, $3, $2}': Uses awk to print the first field ($1), then the third field ($3), and finally the second field ($2), effectively swapping B and C.

Output:

text
A C B

If you want to store the result in a variable or use it in a script, you can do:

bash
result=$(echo "A B C" | awk '{print $1, $3, $2}')
echo "$result"  # Output: A C B
