Thanks guys
. I have played with all the methods you suggested but it does not seem to give me any output
. It works without errors - but just doesn't give output. I should have said I am using the bash shell - could some of these commands not be working properly on my setup? Is there a way I can set it up so it works as you have it.
If it helps - this is the message it gives me for one of the options that doesn't work.
find . -name "a.txt" -exec /usr/bin/awk -F'|' '{printf("%s %d\n", FILENAME, NF-1);nextfile}' {} +
./dir1/a.txt 40
awk: illegal statement 603430
record number 1
Once again thanks in advance for looking at this and so quickly - its really appreciated.

If it is a Solaris system, there is also a good chance that nextfile isn't supported, but that should have generated a clearer error message. Have you tried the other form:
Code:
find . -name 'a.txt' -exec awk -F'|' 'FNR==1{printf("%s %d\n", FILENAME, NF-1)}' {} +|

TRUNCATE(1) User Commands TRUNCATE(1) NAME
truncate - shrink or extend the size of a file to the specified size SYNOPSIS
truncate OPTION... FILE... DESCRIPTION
Shrink or extend the size of each FILE to the specified size A FILE argument that does not exist is created. If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole) reads as zero bytes. Mandatory arguments to long options are mandatory for short options too. -c, --no-create do not create any files -o, --io-blocks treat SIZE as number of IO blocks instead of bytes -r, --reference=RFILE base size on RFILE -s, --size=SIZE set or adjust the file size by SIZE bytes --help display this help and exit --version output version information and exit The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (pow- ers of 1000). SIZE may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round down to multiple of, '%' round up to multiple of. AUTHOR
