Top Forums Shell Programming and Scripting Check Directory for files & Email Post 302967757 by Peasant on Sunday 28th of February 2016 02:52:35 AM
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..
file2=/directory/file/* # lets create a variable which contains all the files in a directory.

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

So the entire code can be :
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
printf "%s\n" "Directory is empty, will do nothing"

cp(1)							      General Commands Manual							     cp(1)

       cp - copy file data

       cp [ -f ] [ -i ] [ -p ] file1 file2

       cp [ -f ] [ -i ] [ -p ] [ -r ] file... directory

       cp [ -f ] [ -i ] [ -p ] [ -r ] directory... directory

       The command copies file1 onto file2.  The mode and owner of file2 are preserved if it already existed; the mode of file1 is used otherwise.
       Note that the command will not copy a file onto itself.

       In the second form, one or more files are copied into the directory with their original file names.

       In the third form, one or more source directories are copied into the destination directory with their original file names.

       -f   Forces existing destination pathnames to be removed before copying, without prompting for confirmation.  The -i option is  ignored	if
	    the -f option is specified.

       -i   Prompts  user  with  the name of file whenever the copy will cause an old file to be overwritten. A yes answer will cause to continue.
	    Any other answer will prevent it from overwriting the file.

       -p   Preserves (duplicates) in the copies the modification time, access time, file mode, user ID, and group ID as allowed  by  the  permis-
	    sions of the source files, ignoring the present umask.

       -r   Copies  directories.  Entire directory trees, including their subtrees and the individual files they contain, are copied to the speci-
	    fied destination directory. The directory, its subtrees, and the individual files retain their original names. For	example,  to  copy
	    the directory including all of its subtrees and files, into the directory enter the following command:
	    cp -r reports news
