Issue
I would like to urldecode a whole file, because there are a few %20 and other ASCII-Numbers in it. I tried this but I do not know how I can call the function defined above in the script in the main routine.
#!/bin/bash
urlencode() {
# urlencode <string>
old_lc_collate=$LC_COLLATE
LC_COLLATE=C
local length="${#1}"
for (( i = 0; i < length; i++ )); do
local c="${1:$i:1}"
case $c in
[a-zA-Z0-9.~_-]) printf '%s' "$c" ;;
*) printf '%%%02X' "'$c" ;;
esac
done
LC_COLLATE=$old_lc_collate
}
urldecode() {
# urldecode <string>
local url_encoded="${1//+/ }"
printf '%b' "${url_encoded//%/\\x}"
}
while IFS= read -r line; do
echo urldecode($line)
done < "$1"
Solution
The format of the program is correct. But you have called your functions not in a correct way.
This is correct way of calling your function in your loop:
while IFS= read -r line; do
urldecode "$line"
done < "$1"
To get the inputs for the function you need to use $1, $2, $3, etc. This is already implemented in your code. As a sample:
# define the function
myfunction() {
echo "$1";
echo "$2";
echo "$3";
}
# call the function
myfunction "First Input" "Second Input" "Third Input"
