[ale] bash question

[Christopher Fowler]

Shat is the output of the command.  What about 'sh -x'

[cfowler at cfowler tmp]$ sh -x ./test.sh 
++ date +%Y%m%d
++ cat date.txt
+ '[' 20030707 -eq 20030707 ']'
+ echo yep
yep


Here is my version:

[cfowler at cfowler tmp]$ cat test.sh 
#!/bin/sh

if [ `date +%Y%m%d` -eq `cat date.txt` ]; then
echo yep
else
echo nope
fi
