How can we find specific type of files i.e. doc pdf files present in nested directories.
command I tried:
$ ls -R | grep .doc
but if there is a file name like alok.doc.txt the command will display that too which is obviously not what I want. What command should I use instead?
We had a similar question. We wanted a list - with paths - of all the config files in the etc directory. This worked:
find /etc -type f \( -iname "*.conf" \)
It gives a nice list of all the .conf file with their path. Output looks like:
/etc/conf/server.conf
But, we wanted to DO something with ALL those files, like grep those files to find a word, or setting, in all the files. So we use
find /etc -type f \( -iname "*.conf" \) -print0 | xargs -0 grep -Hi "ServerName"
to find via grep ALL the config files in /etc that contain a setting like "ServerName" Output looks like:
/etc/conf/server.conf: ServerName "default-118_11_170_172"
Hope you find it useful.

If you have files with extensions that don't match the file type, you could use the file utility.
find $PWD -type f -exec file -N \{\} \; | grep "PDF document" | awk -F: '{print $1}'
Instead of $PWD you can use the directory you want to start the search in. file prints even out he PDF version.
