Linux for loop KSH issue -

-

the following code works fine in 1 system , not other same specs.

system a:

ksh --version version         sh (at&t research) 93u+ 2012-08-01 
uname -a linux servera 2.6.32-431.5.1.el6.x86_64 #1 smp fri jan 10 14:46:43 est 2014 x86_64 x86_64 x86_64 gnu/linux

code:

#!/bin/ksh cd /home/path/ if [ `ls -1 *.log 2>/dev/null |  wc -l` -gt 0 ] ; echo "log files more zero"   f in `ls -1 *.log` ;         echo $f         sleep 1   done fi

output:

log files more 0 file1.log file2.log file3.log

system b:

ksh --version version sh (at&t research) 93u+ 2012-08-01

uname -a linux serverb 2.6.32-431.5.1.el6.x86_64 #1 smp fri jan 10 14:46:43 est 2014 x86_64 x86_64 x86_64 gnu/linux

code:

#!/bin/ksh cd /home/path/ if [ `ls -1 *.log 2>/dev/null |  wc -l` -gt 0 ] ; echo "log files more zero"   f in `ls -1 *.log` ;         echo $f         sleep 1   done fi

output:

log files more 0

and hangs forever .....

any thoughts why ??

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
