Catatan Shell Script

Filename Wildcards

The following characters are interpreted by the shell as filename wildcards, and any word containing them is replaced by a sorted list of all the matching files.

Wildcards may be used in the directory parts of a pathname as well as the filename part. If no files match the wildcard, it is left unchanged. Wildcards are not full regular expressions. Sed, grep, awk etc. work with more flexible (and more complex) string matching operators.

Match zero or more characters.
Match any single character
Match any single character from the bracketed set. A range of characters can be specified with [ – ]
Match any single character NOT in the bracketed set. Read more…

Tutorial ini menjelaskan step-by-step proses instalasi SVN server, serta browsing melalui web server (https) pada webserver apache. Pada dasarnya tanpa membuat koneksi https kita juga sdh bisa mem-browsing isi SVN server melalui web server tetapi pada disini sengaja saya gunakan HTTPS karena kita menggunakan web-based authentikasi, yang tentunya username & password yg ada tidak kita harapkan untuk di-sniff oleh kawan2 kita yg cukup “pintar”. :)
