Files validation
Hi,

I want a script to do the following:

1)I want to find all latest files with extension *.doc and write those files to a log file which i did.
my script: find *.doc -mtime -1 -ls > test.log

2) suppose if there is no such latest files extracts script should write "Server password expires" to log file(test.log)

your prompt help will be much appreciated please.

Find does not return an error when no files are found. Testing the rc ($?) will not help very much.

The log file size will be zero when nothing is found, test that instead:
Code:
find *.doc -mtime -1 -ls > test.log

if [ ! -s test.log ]; then
  echo "Server password expires" >> test.log
fi

I am running Bash 4.x and find (find (GNU findutils) 4.4.2) does return exit code of 1 when the file is not found.

$? contains the exit code of the previous run command. For a success, $? is 0 and for a fail $? is 1. However, there are some gotchas but that's the simple rule.

Nope. From man find:
Code:
EXIT STATUS
       find  exits with status 0 if all files are processed successfully, greater than 0 if errors occur.   This is deliberately
       a very broad description, but if the return value is non-zero, you should not rely on the correctness of the  results  of
       find.

Code:
$ find --version
find (GNU findutils) 4.5.9

$ ls yup
ls: cannot access yup: No such file or directory

$ find . -name 'yup' && echo FOUND || echo NOT FOUND
FOUND

Does that mean that the file named yup exists?

Ok, I am wrong.
