Bash wonkyness on Ubuntu versus RHEL
- by d34dh0r53
Fellow faulters,
I'm playing around with a one liner that I've developed on a RHEL 5.4 box and I have it working perfectly:
TOTAL_RAM=`free | grep Mem: | awk '{ print $2 }'`; \
ps axo rss,comm,pid | awk -v total_ram=$TOTAL_RAM \
'{ proc_list[$2] += $1; } END { for (proc in proc_list) \
{ proc_pct = (proc_list[proc]/total_ram)*100;
printf("%d\t%s\t%0.2f%\n", proc_list[proc],proc,proc_pct); }}' \
| sort -n | tail -n 10
Which outputs something like the following on my RHEL box:
3736 logmon 0.01%
4156 EvMgrC 0.01%
4692 hald 0.01%
5020 ntpd 0.02%
6252 sshd 0.02%
7784 cvd 0.02%
9224 snmpd 0.03%
13068 dsm_sa_datamgr3 0.04%
23320 dsm_om_connsvc3 0.07%
4249864 mysqld 12.90%
However on my Ubuntu 9.04 slice I get this:
awk: run time error: not enough arguments passed to printf("%d %s %0.2f%
")
FILENAME="-" FNR=104 NR=104
33248 console-kit-dae 3.17
I think it has to be bash that is borking something, but I'm really not doing anything that should be that bash specific. The RHEL box is running:
# yum info bash | grep -e Version -e Release
Version : 3.2
Release : 24.el5
And the Ubuntu box:
# apt-cache show bash | grep -e Version
Version: 3.2-5ubuntu1
I haven't dug into this super deeply, and thought I'd ping my fellow johnnys to see if you've ever run across this before.
