67tries to avoid /proc as mush as is possible, so this stuff is
68interesting (to me at least):

83Hi there.

93As a point of reference, here's a slightly tweaked analysis of the
94programs on the system I'm reading your mail on. Basically, I ran the
95following script...
96
97 Q> #!/bin/bash
98 Q> function use() {
99 Q> for Z in $* ; do
100 Q> strings $Z | grep /proc | sed "s=^=$Z ="
101 Q> done
102 Q> }
103 Q> use /{,s}bin/* /usr/{,s}bin/* | sort -u | tee proc-usage
104
105...and then went through it removing comments and print format
106strings. Replace /proc with /dev and you'd soon have an equivalent
107list for that - although I can report that such is MUCH larger...
108
109There are three programs therein that refer to /proc/mounts ...
110
111 /bin/mount
112 /bin/umount
113 /usr/bin/eject
114
115...and, as you stated, none that refer to /proc/atm on this system.
116However, as this is a RedHat Linux 5.0 based system, that's not
117necessarily an up to date reference thereto...
118
