Procinfo gathers system data from /proc and prints it to the screen. The program has been around since the infancy of Linux. There are some patches for procinfo here. Now, Red Hat has been patching this for a long time. Here is a change log for the current patches. The original sources were a bit more difficult to find, and can be found here. Here is a picture of the guy that wrote procinfo:
It took me such a long time to find the original author of procinfo that I felt compelled to put up a picture. So much better than the lists of random people from Red Hat in the SPEC file and the out of date URL. Click on the picture for more info on Sander. He is in a Dutch garage band that is very enjoyable. You can listen to some of their music here. In fact, I highly recommend, if you are following along and compiling this, that you turn on some of the tunes from 1-2-5. It really brightened my day, dear reader.
OK. Some systems don’t have RPM, and so what we need to do is extract the patches and source from the RPM and apply the patches:
# tar -xjf procinfo-18.tar.bz2 # cd procinfo-18 # patch -p1 ../procinfo-14-misc.patch # patch -Np1 -i ../procinfo-14-misc.patch patching file Makefile # patch -Np1 -i ../procinfo-17-mandir.patch patching file Makefile # patch -Np1 -i ../procinfo-17-uptime.patch patching file routines.c # patch -Np1 -i ../procinfo-17-lsdev.patch patching file lsdev.pl # patch -Np1 -i ../procinfo-18-acct.patch patching file procinfo.c patching file procinfo.h # patch -Np1 -i ../procinfo-18-mharris-use-sysconf.patch patching file procinfo.c # patch -Np1 -i ../procinfo-18-maxdev.patch patching file procinfo.h patching file procinfo.c # patch -Np1 -i ../procinfo-18-ranges.patch patching file procinfo.c # patch -Np1 -i ../procinfo-18-cpu-steal.patch patching file procinfo.h patching file procinfo.8 patching file procinfo.c |
Now, let’s tar the whole thing up and re-extract in /usr/local/src:
# tar -czf procinfo-18.2.2.tar.gz procinfo-18.2.2 # # mv procinfo-18.2.2.tar.gz /usr/local/src # cd /usr/local/src # tar -xzf procinfo-18.2.2.tar.gz |
We put a copy of the patched 18.2.2 tarball up here. Let’s compile and install:
cd procinfo-18.2.2 mkdir /usr/man/man8/ make LDLIBS=-lncurses && make install gcc -Wall -Wstrict-prototypes -c -o procinfo.o procinfo.c procinfo.c:19: warning: 'rcsid' defined but not used gcc -Wall -Wstrict-prototypes -c -o routines.o routines.c routines.c:19: warning: 'rcsid' defined but not used gcc -Wall -Wstrict-prototypes -s procinfo.o routines.o -lncurses -o procinfo mkdir -p /usr/bin install -m 755 procinfo /usr/bin/procinfo install -m 755 lsdev.pl /usr/bin/lsdev install -m 755 socklist.pl /usr/bin/socklist mkdir -p /usr/man install -m 644 procinfo.8 /usr/man/man8/procinfo.8 install -m 644 lsdev.8 /usr/man/man8/lsdev.8 install -m 644 socklist.8 /usr/man/man8/socklist.8 # |
Here is how procinfo looks on a CentOS 4 system:
# procinfo Linux 2.6.9-34.EL (buildcentos@build-i386) (gcc 3.4.5 20051201 ) #1 1CPU [main] Memory: Total Used Free Shared Buffers Mem: 507988 467512 40476 0 138968 Swap: 2096472 156 2096316 Bootup: Sat May 13 10:47:08 2006 Load average: 0.01 0.02 0.00 1/62 31761 user : 10:12:38.12 1.3% page in : 0 nice : 0:02:36.30 0.0% page out: 0 system: 6:06:46.95 0.8% swap in : 0 idle : 32d 9:33:49.50 97.9% swap out: 0 steal : 0:00:00.00 0.0% uptime: 33d 1:51:43.64 context : 74975717 irq 0:2858585398 timer irq 8: 1 rtc irq 1: 2 irq 11: 53900252 eth0 irq 2: 0 cascade [4] irq 12: 3 irq 4: 1 irq 14: 4033195 ide0 |
Here is procinfo running with the -f option, which runs continuously:

The above is on a MCJ Root Filesystem, which is just a very plain, vintage 2003 GNU/Linux system that is easy to build yourself. The -a option gives even more details.
