Problem: perl negative look-ahead assertion in multi-line mode

Hello,
I have updated/modified my mysql database in my free website recently.
I have to re-code all my php files such that an extra statement has to

one mysql_query call in some of my php files.
I try to use a negative look-ahead assertion to make such a change as... more »

ksh93, jobs program strings are overwritten somehow
|
| |
Hi,
I have a strange problem with ksh93. After a few weeks or so when
running 'jobs' I only get random strings from previous executed
commands back rather then the real program string.
Example:
This should print 'su -'
sk@solarized:~ $ jobs
[1] + Stopped (SIGSTOP) 48_59.solarized:2,S... more »

`loadkeys' with `--console' option
|
| |
I'm not getting it to work. If I read the man page correctly, with the
`--console' option you can confine the changes to a certain Linux
VT. But there isn't an example... If I provide (for example)
"/dev/tty2" it works, but it is not confined. "/dev/vcs[a]2", whatever
that is, doesn't work (`loadkeys' says can't open).... more »

rsync as root without ssh as root
|
| |
Hello all,
I do my backups with rsync, but since I won't allow ssh root logins, I always thought that I had to physically connect the disk to the PC.
Since I keep my backups offsite, I'd much rather also do the backup via ssh.
I recently saw an comment mentioning that it is possible for rsync to become... more »

converting publication lists to html
|
| |
I have to convert a slew of publication lists to html and because this would be quite tedious, I decided to write a short script to do the work for me.
The simple script below reads each line of the file. If the line has text, it just prints the line. If the line is blank, it prints the closing "</div>" and the opening "<div>" with an in-line style set for the time-being. When it encounters a 2nd consecutive blank line, it just prints the blank line using the flags.... more »
