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:
And just realized I can just actually just do ls -l but it gave me the same behaviour:
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?
Hi,
I have a file which is a result of a script running every two minutes. What I wanted to do is to grep a specific date and time (hour and minute) from the file and then count the occurance of 201.

I've seen several examples of grep showing the filename the string was found in, but what I really need is grep to show the file details in long format (like ls -l would).

Hi guys,
This is probably very easy but I've no idea how to pull this out.
Basically, I need to find errors into a very large logfile. When you grep the ID, the output is like this:

unbuffer
UNBUFFER(1) General Commands Manual UNBUFFER(1)NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected from non-interactive programs. For example, suppose
you are watching the output from a fifo by running it through od and then more.
od -c /tmp/fifo | more
You will not see anything until a full page of output has been produced.
You can disable this automatic buffering as follows:
unbuffer od -c /tmp/fifo | more
Normally, unbuffer does not read from stdin. This simplifies use of unbuffer in some situations. To use unbuffer in a pipeline, use the
-p flag. Example:
process1 | unbuffer -p process2 | process3
CAVEATS
unbuffer -p may appear to work incorrectly if a process feeding input to unbuffer exits. Consider:
process1 | unbuffer -p process2 | process3
If process1 exits, process2 may not yet have finished. It is impossible for unbuffer to know long to wait for process2 and process2 may
not ever finish, for example, if it is a filter. For expediency, unbuffer simply exits when it encounters an EOF from either its input or
process2.
In order to have a version of unbuffer that worked in all situations, an oracle would be necessary. If you want an application-specific
solution, workarounds or hand-coded Expect may be more suitable. For example, the following example shows how to allow grep to finish pro-
cessing when the cat before it finishes first. Using cat to feed grep would never require unbuffer in real life. It is merely a place-
holder for some imaginary process that may or may not finish. Similarly, the final cat at the end of the pipeline is also a placeholder
for another process.
$ cat /tmp/abcdef.log | grep abc | cat
abcdef
xxxabc defxxx
$ cat /tmp/abcdef.log | unbuffer grep abc | cat
$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
abcdef
xxxabc defxxx
$
BUGS
The man page is longer than the program.
