Question

以下代码在一个系统中正常工作，而在具有相同规格的其他系统中工作正常。

系统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

代码：

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

输出：

Log files are more than Zero
file1.log
file2.log
file3.log

系统B：

ksh --version 版本sh（AT＆amp; T Research）93u + 2012-08-01

代码：

#!/bin/ksh
cd /home/path/
if [ `ls -1 *.log 2>/dev/null |  wc -l` -gt 0 ] ; then
echo "Log files are more than Zero"
  for f in `ls -1 *.log` ; do
        echo $f
