Help with grep to show date/time of file

Hi,


This is similar to what's been asked in the post below:

grep to show date/time of file the string was found in.


The solution sort of work / not work, the problem is if there is no match, then xargs does a full listing. That is if it found file/s that matches the search string and hence file exist, it does list the files but if it doesn't find a match it do a full listing instead Smilie


See example below:


Code:
$: ls -ltr
total 16
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file1
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file2
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file3
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file4
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file5
-rw-r-----   1 tester   omg            15 Mar 19 09:36 corrupt.txt
$: grep -il "bad" * | xargs ls -l
-rw-r-----   1 tester   dba           15 Mar 19 09:36 corrupt.txt
$: grep -il "corrupt" * | xargs ls -l
total 16
-rw-r-----   1 tester   omg            15 Mar 19 09:36 corrupt.txt
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file1
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file2
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file3
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file4
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file5
$: uname -a
SunOS [hostname] 5.11 11.3 sun4v sparc sun4v
$: cat corrupt.txt
BAD FILE FOUND

And just realized I can just actually just do ls -l but it gave me the same behaviour:


Code:
$: ls -l `grep -il "bad" *`
-rw-r-----   1 tester   omg            15 Mar 19 09:36 corrupt.txt
$: ls -l `grep -il "corrupt" *`
total 16
-rw-r-----   1 tester   omg            15 Mar 19 09:36 corrupt.txt
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file1
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file2
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file3
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file4
-rw-r-----   1 tester   omg            0 Mar 19 09:36 file5

I guess this is the expected behavior but kinda hoping it'll just do nothing if it doesn't find any or print something maybe instead? Any suggestion?

NAME
jstest-gtk - joystick testing and configuration tool SYNOPSIS
jstest-gtk [options]... [device] files... DESCRIPTION
jstest-gtk is a simple joystick tester based on Gtk+. It provides a list of attached joysticks, a way to display which buttons and axis are pressed, a way to remap axis and buttons and a way to calibrate your joystick. Even when your joystick is working mostly fine, you might want to give it a try, as the calibration lets you get rid of overlarge default deadzones that many joysticks use and then is a noticeable problem in some games. USAGE
jstest-gtk is mainly a graphical interface to check that your joysticks and pads work properly. You can find precise information on each axis, you can optionally recalibrate it and also change the mapping. If you run the program without parameters, you will get a window showing all the joystick devices in your system (there can be more than one). When you double click on one of them, you will get a newer window with detailed information about its axis and buttons. There are two buttons in the detailed window called "Mapping" adn "Calibration", that allows you to reconfigurate the device. If you run the program with a device as an argument (for example /dev/input/js0), you will get the detailed window for that device directly, without getting the whole list of joysticks in the system. Calibration of the axis consists in a simple window in which you set the values that go directly into the operative system configuration, without doing any changes on them. They're divided in range and dead zone (or center). In both of them you have to set a minimum and a max- imum. You also have a checkbox for inverting the axis. Values are changed and applied in the same instant that you modify them, there's no need for clicking anywhere or doing anything else for applying the changes. OPTIONS
These program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). -h, --help Display help information and exit -v, --version Display version information and exit SEE ALSO
