Question

I have code matching:

if [ $LAST_MODIFIED -lt 3600 || ! -f "$i" ]; then
    wget $WGET_OPTS $BASE$i
    LAST_MODIFIED=`echo "\`date +%s\` - \`stat -c %Y $i\`" | bc`
    if [ $LAST_MODIFIED -lt 500 ]; then
        $FILES_MODIFIED++
    fi
fi

$i is defined via

for i in `/bin/grep ".gz" index.html | awk -F\" '{print $2}'`

however, bash tells me

[: missing `]'

and

-f: command not found

Why?

Answer 1

Should be

if [ $LAST_MODIFIED -lt 3600 ] || ! [ -f "$i" ]; then

[ (and !) are shell built-ins. They are not part of the syntax for if.
