rc script running twice ???

[Drew Van Zandt]

I've never used the ps f view (yes, I know...how odd); handy.

root       470  1.1  2.4   2992  1516 ttyS0    Ss+  00:00   0:00 /bin/sh
/etc/init.d/rc 2
root       496  0.1  1.9   2808  1232 ttyS0    S+   00:00   0:00  \_ /bin/sh
/etc/rc2.d/S40init_xuarts start
root       498  0.0  0.8   2808   504 ttyS0    S+   00:00   0:00      \_
/bin/sh /etc/rc2.d/S40init_xuarts start
root       500  0.1  0.9   1676   576 ttyS0    S+   00:00   0:00          \_
sed s/ttyname=//

root       502  0.0  0.4   1712   308 ?        Ss   00:00   0:00
/usr/local/bin/xuartctl -d --speed=115200 --mode=7e1 -p 1
root       503  0.0  0.3   1720   244 ?        Ss   00:00   0:00
/usr/local/bin/xuartctl -d --speed=115200 --mode=7e1 -p 1

Note the -d daemonizes xuartctl in the script below:
ts7500:/etc/init.d# more init_xuarts.sh
#!/bin/sh
# Server for all first.
xuartctl -d
# Barcode
ln -s -f `/usr/local/bin/xuartctl -d --speed=115200 --mode=7e1 -p 1 2>&1
|sed s/ttyname=//` /dev/barcode
# Copleys
ln -s -f `/usr/local/bin/xuartctl -d --speed=9600 --mode=8n1 -p 2 2>&1 |sed
s/ttyname=//` /dev/copley
# Watlows
ln -s -f `/usr/local/bin/xuartctl -d --speed=38400 --mode=8n1 -p 5 2>&1 |sed
s/ttyname=//` /dev/watlow
