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
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?

This is probably very easy but I've no idea how to pull this out.

dgrep
DGREP(1) Debian-goodies documentation DGREP(1)NAME
dgrep, degrep, dfgrep, dzgrep -- grep through files belonging to an installed Debian package
SYNOPSIS
dgrep [most grep options] pattern package...
dgrep --help
DESCRIPTION
dgrep invokes grep(1) on each file in one or more installed Debian packages.
It passes the package argument(s) to dglob(1) to retrieve a list of files in those packages. You can use POSIX regular expressions for the
package names.
If dgrep is invoked as degrep, dfgrep or dzgrep then egrep(1), fgrep(1) or zgrep(1) is used instead of grep.
OPTIONS
dgrep supports most of grep(1)'s options. Please refer to your grep documentation (i.e. the manpage or the texinfo manual) for a complete
listing. Only a few options are excluded because they do not conform with the intended behaviour, see the list below.
Options of grep that are not supported by dgrep
-r, --recursive, -d recurse, --directories=recurse
-d read, --directories=read
dgrep searches only in the "normal" files of a package. It skips all directories and symlinks. Therefor the options of grep that are
specific to directories are not supported.
