This project was done in the context of the System's Programming semester project at HEPIA.

Authors: David Gonzalez & Claudio Sousa

The project consists in developing a tool that creates a dynamic folder containing the result of a file search.

The tool is used by specifying a destination folder, a source folder and an optional filtering expression. The destination folder is created and inside is maintained an up-to-date list of symbolic links pointing to the files found within the source folder matchin the filtering expression.

The filtering expression syntax is closely inspired by the find command. The user may filter files according to the following criteria: name, group, owner, group owner, permission, size, access/modified/metadata time.

The criteria above may be combined using logical operators (and, or, not) or parenthesis.

This example links all backup files that are bigger that 10 mega whose creation date is older than 30 days:

./searchfolder destdir backup -name .bkp -size +10M -ctime -30d

This example links all files on the system whose permission are for everyone and the group owner is root or the owner is not root:

./searchfolder destdir / (-group root -or -not -user root) -and -perm 777
