It's certainly not going to work if you force the string to contain quotes. It will search for files with literal quotes in their names.

Also, just repeating the list won't work either. You need -name a -o -name b -o -name c, etc.

Paths can be used as-is, since find takes a literal list there.

You don't even need arrays here. The shell is perfectly capable of splitting strings at need.

So I'd just assemble a list in the $1, $2, ... variables and use it. Then you can pretty much just find "$@"

Code:

#!/bin/sh
paths="/test/a /test/b"
keywords="*car* *food*"

set -f # prevent *car* from globbing here
for X in $keywords
do
        if [ -z "$1" ]
        then
                set -- -name "$X"
        else
                set -- "$@" -o -name "$X"
        fi
done

echo find $paths -type f -ctime 1 '(' "$@" ')'

Code:

$ ./findl.sh

find /test/a /test/b -type f -ctime 1 ( -name *car* -o -name *food* )

$

It works in any and every bourne shell I have since it doesn't use arrays.

BASHBUG(1)							      bashbug								BASHBUG(1)

NAME

       bashbug - report a bug in bash

SYNOPSIS

       bashbug [--help] [--version] [bug-report-email-addresses]

DESCRIPTION

       bashbug is a utility for reporting bugs in Bash to the maintainers.

       bashbug will start up your preferred editor with a preformatted bug report template for you to fill in. Save the file and quit the editor
       once you have completed the missing fields.  bashbug will notify you of any problems with the report and ask for confirmation before
       sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed
       by giving a comma separated list of bug-report-email-addresses.

       If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent.

OPTIONS

       --help
	      Show a brief usage message and exit.

       --version
	      Show the version of bashbug and exit.

       bug-report-email-addresses
	      Comma separated list of recipients' email addresses. By default the report is mailed to both the GNU developers and the Debian Bash
	      maintainers.

ENVIRONMENT

       DEFEDITOR
	      Editor to use for editing the bug report.

       EDITOR
	      Editor to use for editing the bug report (overridden by DEFEDITOR).
