I am using the FIND command on a number of directories stored in FDIR array to
execute HEAD on each file. How can I adapt the code so users can also include
files as well as directories?
hn=8
nf=${#fdir[@]}
for (( i=0 ; i < $nf ; i++ )); do
find "${fdir[$i]}" -type f \
-exec head -v -n "$hn" '{}' +
done
The synopsis of the GNU find command is
find [-H] [-L] [-P] [-D debugopts] [-Olevel] [starting-point...] [expression]
where [starting-point...] is zero or more paths. There is nothing stopping the
user from passing files as starting points
Example, given:
$ cat subdir/somefile
foo
bar
baz
then
$ find subdir/somefile -
type
f -
exec
head -n 2 {} +
foo
bar
I could just do
find
"
${fdir[@]}
"
-
type
f -
exec
head -v -n
"
$hn
"
'{}'
+
regardless of the mix of directories and files in FDIR.
But is this the right and proper way to use the FIND command?
