Subject: new and improved mkdir(1) (#149) Index: bin/mkdir.c 2.11BSD Description: Mkdir(1) in 2.11BSD is missing the '-p' option. Repeat-By: Examination. Fix: I had a need to make directories where the intermediate path did not already exist. I noticed that newer versions of 'mkdir' present beginning in 4.3Reno had a '-p' option to perform this task. Luckily the program is small enough that it compiled straight away without any porting effort. The same, alas, was not true of the manpage - i manually converted the man page from 'mandoc' to 'man' macros. 1) mv /usr/src/bin/mkdir.c /usr/src/bin/mkdir.c.old 2) mv /usr/src/man/man1/mkdir.1 /usr/src/man/man1/mkdir.1.old [if you are sufficiently trusting you can simply rm the old files] 3) unshar the file below 4) cd /usr/src/bin make mkdir install -s mkdir /bin/mkdir 5) /usr/man/manroff /usr/src/man/man1/mkdir.1 > /usr/man/cat1/mkdir.0 ===================================cut here=========================== #! /bin/sh # This is a shell archive, meaning: # 1.
