Using variable to store of find command
Hello Experts

I am newbie to unix and writing one script to make archive files

Problme i am facing is : I have used find command to find the type of files and I am storing find command results in a variable.

When I echo the variable I can see that path is printed properly but when i am making non-enpty or null check on variable it find variable as empty.

var=find . -name ...etc

echo $var ...prints properly but

if(! -z var) (ignores if and goes to else ...it means to me is that variable is empty)

can you please tell how to check if the variable is not null or contain string.

thanks for looking into it.

shar

SHAR(1) 						    BSD General Commands Manual 						   SHAR(1)

NAME

     shar -- create a shell archive of files

SYNOPSIS

     shar file ...

DESCRIPTION

     The shar command writes a sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line op-
     erands.  Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly).

     The shar command is normally used for distributing files by ftp(1) or mail(1).

EXAMPLES

     To create a shell archive of the program ls(1) and mail it to Rick:

	   cd ls
	   shar `find . -print` | mail -s "ls source" rick

     To recreate the program directory:

	   mkdir ls
	   cd ls
	   ...
	   <delete header lines and examine mailed archive>
	   ...
	   sh archive

SEE ALSO

     compress(1), mail(1), tar(1), uuencode(1)

HISTORY

     The shar command appeared in 4.4BSD.

BUGS

     The shar command makes no provisions for special types of files or files containing magic characters.  The shar command cannot handle files
     without a newline ('
') as the last character.

     It is easy to insert trojan horses into shar files.  It is strongly recommended that all shell archive files be examined before running them
     through sh(1).  Archives produced using this implementation of shar may be easily examined with the command:

	   egrep -v '^[X#]' shar.file
