Full Discussion: Check Directory for files & Email

file2 variable will expand to multiple values (file names from directory specified)

It cannot be used in if [ -f $file2 ] .. , the error will be to many arguments (it expects one not a list of files).

I cannot be sure about the exact requirement from your post..
Code:
file2=/directory/file/* # lets create a variable which contains all the files in a directory.
file=/usr/local/mailfile.txt


if [ -f ${file2} ]; # if a file exists (this will work only if a one file is a file2 directory)
 then
  ls -la $file2 > $file # list all the files into a txt file  ? You could do these without any variables or conditions ...
fi
....

So the entire code can be :
Code:
ls -al /directory/file/*  > ${file}.txt
if [ -s ${file}.txt ]; then # if ls output gave something to file.txt (there are files)
... mail or whatever
else
printf "%s\n" "Directory is empty, will do nothing"
fi

LEARN ABOUT SUSE

lzcmp

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
