How this works
| Command | Description |
|---|---|
| s=$(echo "this is just some text" | rev) |
| hex="" | Creates an empty variable hex to store the hexadecimal values. |
| for (( i=0; i<${#s}; i++ )) | loops through each character in the s string. |
| hex+="\((printf "%02x" "'\)")" | Converts each character to its hexadecimal value using the printf command and appends it to the hex variable. |
| echo ${hex^^} | Prints the hex variable in uppercase (uppercase hexadecimal values). |
#!/bin/bash
s=$(echo "this is just some text" | rev)
hex=""
for (( i=0; i<${#s}; i++ )); do
hex+="$(printf "%02x" "'${s:i:1}")"
done
echo ${hex^^}
