UNIX for Dummies Questions & Answers

Hi there. Linux newbie and I'm trying to find commands to:

Display number of executable files in a directory that i supply and list them in alphabetical order

Back up all the files in the current irectory to a directory i supply, creating that directory if it's not allready there

Cound number of occurances of a file name that i provide in the file system.

Any help would be really appreciated!
Cheers

Well to find out whether a file is executable under a directory, I cannot think of any command as such present in unix, I doubt whether there is any. You can use this script to find out the executable file

Code:

#!/bin/sh

for i in `ls -1`
do
        if [ -x $i ]
        then
                echo $i
        fi
done

Others I need to try

For second query

cp -R JUNK JUNK1

JUNK is the existing directory
JUNK1 is the non-existing directory, if the directory exists then JUNK will be its sub-directory

For third query

find ./ filename

It will search the whole of the file system and will take lot of time

That's great thanks very much, but do you know how I would get it to *count* the number of occurances of a filename within the file system, rather than just list the filenames?

Thanks for your help so far, much appreciated.

find ./ filename | grep -x "filename" | wc -l

It would have been better if you had come with this solution rather than me, just try around and play with unix you can find lot more stuffs and you can also learn more

Cheers

You can use also this, this is much simpler

find / -name filename | wc -l
