Small bash utilities created as assignments for my Introduction to UNIX class at Charles University in Prague.
They demonstrate the usage of awk, sed, named pipes and file descriptors as well as other basic UNIX tools.
Utility for mirroring contents of folders via FTP, created as a project for Introduction to UNIX class at Charles University in Prague.
usage: ./FTPmirror.sh sourcePath destinationPath [{s|a|m}|d|L|h]
Parameters:
$0 sourcePath destinationPath options
sourcePath # Location of the folder to be mirrored
#
# Examples:
# .
# backups/
# /var/backups/
# user@example.com # will be asked for password interactively
# user:password@example.com:path/
destinationPath # Destination of mirroring
# Examples:
# .
# backups/
# /var/backups/
# user@example.com # will be asked for password interactively

# modification date overwrite files with similar
# names in destionationPath.
# Moreover, all files that are present in
# destinationPath but are not present in
# sourcePath are removed.
#
a # All - In case of a conflict all files in destination become
# overwritten by their versions from sourcePath
#
m # Modified - In case of a conflict only files with older
# modification date overwrite files with similar
# names in destionationPath
Special parameters:
-v # Display script version number and quit
-h # Display this help message and quit
Dependencies:
