Final answer:
To compute all possible letter permutations of a word using a bash script, you can utilize commands such as echo, grep, and sort.
Step-by-step explanation:
To write a bash script that computes all possible letter permutations of a word, you can use the built-in echo command in combination with grep and sort.
Here is an example script:
#!/bin/bash
word=$1
permutations=$(echo $word | grep -o . | sort | tr -d '
')
echo $permutations
This script takes a single word as a command line argument and uses grep -o . to split the word into individual characters, then sorts them using sort, and finally removes the newline character using tr -d '
'. The result is printed using echo.
