I must admit, I like jim mcnamara's neat response. It made me wonder about the string often all of the kinds of Norway as an example where the string might exist embedded in another word. Is this a problem to you?
By adding the -w flag, you can adjust the output:-
Of course, this may or may not be useful, but I thought I should add it into the mix.
When I type a command at the command line it supplies one result and the exact same command in a script
egrep '^01|^02|^03|^04' file > fileout
count = 29353
same count in the script yields a count of 23492
is there any reason this could be happening. (1 Reply)
On our one HP-UX 11i box, we have some very long paths defined. When I want to check on our user processes running, the resulting paths are chopped off. /xyz/abc/123/......./server/b is really a process running in the ..../server/bin directory. Is this a terminal problem or buffer length... (1 Reply)

I'm using the command grep -l XYZ to get a list of files containing the string XYZ. Then I using the comand ls -l ABC to get the create date timestamp of the each file. I've tried combining the comands using the pipe command, grep -l XYZ | ls -l, but its not working. What am I doing wrong? (3 Replies)

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.
