Combining enscript, find, iconv and ps2pdf

Question

I'm trying to write a small bash script that'll convert source files in a directory to a .pdf. The steps are these

• Locate files with find
• execute iconv on the files converting the character encoding from utf-8 to iso-8859-1 via finds -exec
• pass this output through enscript and eventually ps2pdf

The only reason I've added iconv is that enscript does not support utf-8. So far I've made the following mess:

#!/bin/bash
enscript --portrait --columns=1 --header ' $n|'"$2"'|%F  Page $% of $=' --highlight='java' --line-numbers --output='-' --color --font='Courier8' `find $1 -name '*.java' -type f -exec iconv -f utf-8 -t iso-8859-1 {} +` | ps2pdf - "$2"'.pdf'

Running it give me this output: enscript: invalid option -- ',' Try `enscript --help' for more information.

Edit: It did not give that error before I added -exec iconv.
2. edit: The original formulation I made was vague I see now. Heres the original script I tried to modify:

#!/bin/bash
`which enscript` --portrait --columns=1 --header ' $n|'"$2"'|%F  Page $% of $=' --highlight='java' --line-numbers --output='-' --color --font='Courier8' `find $1'/src/' -name '*.java'` | ps2pdf - "$2"'.pdf'

./script.sh target_dir output_file_name

The original script combines all source files in a folder recursively into one single pdf with each file starting at a fresh page. Maybe I just got to live with having to do this in two steps. First converting charset and then converting to pdf.

Answer 1

Create a java2ps script to easying the parameter handling

#!/bin/bash

export ENSCRIPT="
--portrait
--columns=1
--font=Courier8
--highlight=java
--color
--line-numbers
--output=-
"

iconv -f utf-8 -t iso-8859-1 "$1" \
| enscript --header=' $n|'"$1"'|%F  Page $% of $='

Now, the execution is simple

find -name '*.java' -type f -exec ~/java2ps {} \; | ps2pdf - > all.pdf
