Just for fun:

Add the following to your /etc/csh.cshrc:
setenv LSCOLORS ExGxFxdxCxegedabagExEx
setenv CLICOLOR yes
set prompt = ‘[%B%n@%m%b] %B%~%b%# ’
set autolist
bindkey “^W” backward-delete-word
bindkey -k up history-search-backward
bindkey -k down history-search-forward

And execute:
sed -i.bak -E s/set\ prompt/#set\ prompt/g /root/.cshrc

Then re login.

Source code cleanup:

sed -i '' -E s/\ \	/\	/g *.c *.h
sed -i '' -E s/^\ \ \ \ \ \ \ \ /\	/g *.c *.h
sed -i '' -E s/\	\ \ \ \ \ \ \ \ /\	\	/g *.c *.h
sed -i '' -E s/\ +\$//g *.c *.h

grep cgi-bin scripttime | cut -f6,8 -d’ ’ | sed -E s/\\\?.+//g | grep cgi-bin | sort | uniq -c | sort > statis

Where scripttime is a log with %T (script execution time) log. The above command line will obtain execution time, script name from log, then sort it by the execution time, then have a counted unique.

Merge FreeBSD-CURRENT changes to delphijfork:

It turns that I need to set up my own cvsup server so I can deploy my fork elsewhere. Here comes how.
