bash script command not found

Question

I'm trying to run bash script written in here: Link

I fixed script above like this:

#!/bin/bash

keyFile=video.key
openssl rand 16 > $keyFile
encryptionKey=cat $keyFile | hexdump -e '16/1 "%02x"'

splitFilePrefix=stream
encryptedSplitFilePrefix=enc/${splitFilePrefix}

numberOfTsFiles=ls ${splitFilePrefix}*.ts | wc -l

for (( i=1; i<$numberOfTsFiles; i++ ))
 do
 initializationVector=printf '%032x' $i
 openssl aes-128-cbc -e -in ${splitFilePrefix}$i.ts -out ${encryptedSplitFilePrefix}$i.ts -nosalt -iv $initializationVector -K $encryptionKey

ran script like this: ./script.sh

but bash keeps yelling like this:

./script.sh: line 5: video.key: command not found

./script.sh: line 10: stream0.ts: command not found
0

./script.sh: line 17: syntax error: unexpected end of file

I have no idea why..

I searched about the error and checked ~/.rnd owner, .sh file chmod +x, $PATH problems, but all of them did not work.

You are missing some characters in your script, in the original, line 5 is for example like this: keyFile=”video.key”, line 10: should be like this: splitFilePrefix=”stream” etc. Pls check the original script again — papacito

This line:

encryptionKey=cat $keyFile | hexdump -e '16/1 "%02x"'

is trying to execute cat, but you are not using command substitution. It should be:

encryptionKey=$(cat "$keyFile" | hexdump -e '16/1 "%02x"')

similarly, you need:

numberOfTsFiles=$(ls ${splitFilePrefix}*.ts | wc -l)

and need a done after the loop:

for (( i=1; i<$numberOfTsFiles; i++ ))
do
   # ...
done
