SYNOPSIS

      escan [OPTIONS]... [OBJECT]...

DESCRIPTION

      Scans and cleans directories and files for viruses and other malwares.

OPTIONS

Scan Actions
These option are the action to be taken in case of any infected object found by scanner.
-ly, --log-only
Only Report infection found / detected in the scanned log. No action on infected
files.
-dl, --disinfect-log
Will try to Disinfect, if not possible shall Report infection found / detected
in the scanned log.
-dd, --disinfect-delete
Will try to Disinfect, if not possible shall delete the infected object.
-dq, --disinfect-quarantine
Will try to Disinfect, if not possible shall quarantine (Default) the infected object.
-dr, --disinfect-rename
Will try to Disinfect, if not possible shall rename the infected object.
-dp, --disinfect-prompt
Will try to Disinfect, if not possible shall prompt for the action to be taken on the infected object.
Following Actions will be prompted:
Do Nothing
Delete
Quarantine
Rename
Cancel Scan
-di, --delete-infected
Will Delete the Infected object.
-ri, --rename-infected
Will Rename the Infected object.
-qi, --quarantine-infected
Will Quarantine the Infected object.
-pr, --prompt
Will Prompt for an Action to be taken on the infected object without trying to disinfect it.
-qp, --quarantine-path*
Sets the Quarantine Path for the infected object. It sets action as quarantine.
While setting Quarantine Path, make sure that user has write permission to
directory.
Example
# escan -qp /var/MicroWorld/var/quarantine/escan
-re, --rename-extension*

before extension value.
Example
# escan -re mwt
</B>NOTE:</B> Quarantine path and Rename extension Parameters are descarded, if action is set as ’prompt’. In that case default qurantine path
’/var/MicroWorld/var/quarantine/escan’ and default rename extension ’.mwt’ will be used.
Also, provide only one of -qp or -re, otherwise both the parameters will be ignored and default values will be used.

  Recursion Options</font>
      -rr, --recursion
           Will Scan files in the Directories and in the Sub-Directories recursively.
           By default this option is enabled.
      -rr-, --no-recursion
           Will scan only the files in the directory of subject to scan without following
           any sub-directory in the path.
      -lk-, --no-symlink
           While scanning the object(s), any symbolic link in the path will be will not be
           followed and will be ignored. By default, all symbolic link scanning is disabled.
      -lk, --all-symlink
           While scanning the object(s), any symbolic link in the path will be resolved and

           While resolving the symbolic link in scan path or object, if any object is found
           on other device (physical device or logical file system), the object will be
           ignored and path will not be followed. By default, any cross file system scanning
           is diabled.
      -cr, --cross-fs
           While resolving the symbolic link in scan path or object, if object(s) is/are
           foundon other device, the path will be followed for scanning.

# escan -sx exe /home
To scan files having extensions exe or com
# escan -sx exe,com /home
-xx, --exclude-ext
