indication of find activity - bash script
Hi All,

I wanted to show on stdout that a file was found right after it happens due to indicate the activity of long search. Further more I want to store the result of the find in a file.

I have tried this:
Code:
echo -n "Searching"
find . -name Makefile -type f -print -exec echo -n "." \; > testPaths.log

Unfortunately dots are written to the file.
How could I separate output of -exec and result of find? or How could I indicate the find activity?

What about:
Code:
echo -n "Searching"
find . -name Makefile -type f -print -exec echo -n "." | tee -a testPaths.log

?

Or:

Code:
find . -name Makefile -type f 2> /dev/null | while read FILE; do printf "."; echo $FILE > testPaths.log; done

Code:
find . -name Makefile -type f -print -exec echo -n "." | tee -a testPaths.log

prints dot and path to both file and stdout due to piping (dot is printed right after a file is found)

while

Code:
find . -name Makefile -type f 2> /dev/null | while read FILE; do printf "."; echo $FILE > testPaths.log; done

prints the right characters to right places, but the printing of dot is execute just after the find finishes its work on the whole directory set.

Any other idea?

(at this point the piping mechanism is not clear for me: why tee is executed after each file found and why not executed while (just at the end)? Maybe this is the behaviour of while (like xargs echo)?)

I don't know if it works but I think it should work ^^'
Code:
find . -name Makefile -type f -print -exec tee -a testPaths.log | echo -n "."

What it is supposed to do:
first writes the found file to testPaths.log and then echo a dot, not the other way around
Sorry for explaining so bad ^^'
btw @scottn: if you take a look at find's man page:
Quote:
-exec command ;
Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of `;' is encountered.
maybe thats why it doesn't print the dot directly to stdout? Sorry I could also be terribly wrong about it ^^'

Why would it do that?

Perhaps it just runs too quickly for you to see.

Try putting a sleep (or usleep) in to test.

Hi.

I didn't use -exec.

The dots print perfectly fine, just, as I said too quickly. But when it finds a file, it prints a dot.
