9 | # Example: Running 'mw_create_redirect_day_month.sh 2022' creates | |
10 | # directory 'wikicode' in working directory. It then populates it | |
11 | # with text files with names ranging from '2022-01-01' through | |
12 | # '2022-12-31', taking leap years into account. Each text file | |
13 | # contains one line of wikicode redirecting a [[YYYY-mm-dd]] link to | |
14 | # [[YYYY-mm#YYYY-mm-dd]]. For example: | |
15 | # | |
16 | # 2022-02-28.txt: | |
17 | # ``` | |
18 | # #REDIRECT [[2022-02#2022-02-28]] | |
19 | # ``` | |
20 | # | |
21 | # This is useful in combination with Mediawiki's | |
22 | # 'maintenance/importTextFiles.php' script that imports text files | |
23 | # into a wiki, using each text file's name as a new page title; by | |
24 | # default it does not clobber (overwrite) pages if they already | |
25 | # exist. | |
