title: openssl unknown option error
body: <p>I ran this script below:</p>
  
  <pre><code>#!/bin/bash
  
  keyFile=video.key
  openssl rand 16 &gt; $keyFile
  encryptionKey=$(cat $keyFile | hexdump -e '16/1 "%02x"')
  
  splitFilePrefix=stream
  encryptedSplitFilePrefix=enc/${splitFilePrefix}
  
  numberOfTsFiles=$(ls ${splitFilePrefix}*.ts | wc -l)
  
  for (( i=1; i&lt;$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
   done
  </code></pre>
  
  <p>right after the execution, the bash gives me an error:</p>
  
  <pre><code>./script.sh: line 14: fg: no job control
  unknown option '9d268d620c68938b4578c3f299c91a1a'
  options are
  -in &lt;file&gt;     input file
  -out &lt;file&gt;    output file
  -pass &lt;arg&gt;    pass phrase source
  -e             encrypt
  -d             decrypt
  -a/-base64     base64 encode/decode, depending on encryption flag
  -k             passphrase is the next argument
  -kfile         passphrase is the first line of the file argument
  -md            the next argument is the md to use to create a key
                   from a passphrase.  One of md2, md5, sha or sha1
  -S             salt in hex is the next argument
  -K/-iv         key/iv in hex is the next argument
  -[pP]          print the iv/key (then exit if -P)
  -bufsize &lt;n&gt;   buffer size
  -nopad         disable standard block padding
  -engine e      use engine e, possibly a hardware device.

  <p>I read openssl manual and thought either -K or -iv part is wrong, but couldn't figure out which option and why is it wrong</p>
