strange output of regex

vinaytp · 11-25-2009, 11:20 PM

Hi all...

Code:

[vinay@TEG test]$ echo grapes>"text sample2"
[vinay@TEG test]$ cat "`ls text*le2`"
grapes
[vinay@TEG test]$ cat "`ls text*2`"
cat: text2
text sample2: No such file or directory

Here I feel 3rd command should display contents of file "text sample2"...The output is really looking strange...How is this working ?

I got the concept.....
shell is giving the cat command a single parameter text2..

Code:

web31337@srvr:/tmp$ echo grapes>"text sample2"
web31337@srvr:/tmp$ cat "`ls text*le2`"
grapes
web31337@srvr:/tmp$ cat "`ls text*2`"
grapes

it works fine for me. works on debian lenny (2.6) and even on my freebsd vds.
i simply copypasted these commands from your code.
