Hello Don,

Below is the print containing the Linux version, shell used (bash) and script ( ls -lst abc*.txt ). As you can see there are another file names
that not begin with abc in the list. They are highlighted in red.
Code:
bbt@ax-1:~>% uname -a
Linux ax-1 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x8664 x8664 x8664 GNU/Linux
bbt@ax-1:~>%
bbt@ax-1:~>% echo $SHELL
/bin/bash
bbt@ax-1:~>%
bbt@ax-1:/voddf/bbts/ax-abc/files>% ls -lst abc*.txt

That is very strange.

Code:
$ touch zabc
$ ls abc*
ls: cannot access abc*: No such file or directory
$

And yes, it is a difference in your shell. The expansion of * happens before ls runs.

BASH is very configurable, it's possible somebody enabled a bizarre option by default. It's also possible for the value of $SHELL to be wrong under some circumstances. Post the output of shopt in that shell, please.

Hello Corona688,

I've change to ksh and the output of the same ls command prints correctly only files that begin with abc. It seems is an issue with bash shell like you said.

Below is shopt print in bash shell.
Code:
bbt@ax-1:/voddf/bbts/ax-abc/files>% shopt
cdable_vars     off
cdspell         off
checkhash       off
checkwinsize    on
cmdhist         on
dotglob         off
execfail        off
expand_aliases  on
extdebug        off
extglob         off
extquote        on
failglob        off
force_fignore   on
gnu_errfmt      off
histappend      off
histreedit      off
histverify      off
hostcomplete    on
huponexit       off
interactive_comments    on
lithist         off
login_shell     on
mailwarn        off
no_empty_cmd_completion off
nocaseglob      off
nocasematch     off
nullglob        off
progcomp        on
promptvars      on
restricted_shell        off
shift_verbose   off
sourcepath      on
xpg_echo        off

Thanks for the help.

BASH doesn't usually do this. Have you customized your ~/.login or ~/.bashrc or ~/.bash_rc etc files at all? What's the value of IFS in BASH? printf "%s" "$IFS" | hexdump -C

Or there could be something strange like programmable completion gone awry happening.

Those look normal enough. I'm not sure what's happening here.

I haven't change anything, this is an equipment that they gave me access to some folders only with a generic user.

The output of IFS is:
Code:
 printf "%s" "$IFS" | hexdu mp -C
00000000  20 09 0a                                          | ..|
00000003

By the way, what is IFS?

Regards

The characters the shell uses to separate input fields are listed in IFS (by default space, tab, and newline; which is what you see in your output).

Maybe we have some backspaces in some of these filenames. Please post the output from the command:
Code:
printf "%s\n" *00z* *113*abc*.txt abc*113*.txt|od -cb

Then why wouldn't KSH see them?
