Hello Nakul,

Here is the hint for you.

1- you can check the number of files by ls command with using wc command or by awk command.

2- you can then look for the man page for find command which have all the severa; options to search files older than specific number of days.

3- You can use exec command to delete those files within find command itself.


Could you please try the steps and let us know where you have stuck.



Thanks,
R. Singh

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

NAME
shar -- create a shell archive of files SYNOPSIS
shar file ... DESCRIPTION
shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands. Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly). shar is normally used for distributing files by ftp(1) or mail(1). SEE ALSO
compress(1), mail(1), tar(1), uuencode(1) BUGS
shar makes no provisions for special types of files or files containing magic characters. 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 HISTORY
The shar command appears in 4.4BSD. SECURITY CONSIDERATIONS
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 4.4BSD June 6, 1993 4.4BSD
