This one is a bit too challenging for me... Hopefully you guys can help.
Let's say I have a log file called:
"$MW_HOME/user_projects/domains/IDMDomain/servers/wls_ods?/logs/wls_ods1-diagnostic.log"
In this log file I want to search for "DIP-10219". When I execute this
I get this output.
Based on this output, I need to write a wrapper that executes something with the output in red above.
So I would like to know, how to:
1. Create a loop to search through the logfile
2. Pass the entries to a second command (ldapdelete), remove everything before "cn=" and after "=com"
How would I grep for password file entry without using
grep 'username' /etc/passwd?
perhaps with who?
I want to create alias that will find the password file entry regardless of the user who is using it.
I am trying to get the same exact line from the file entry like:
Name : Password : UserID... (7 Replies)

I have 1300 files (SearchFiles0001.txt, SearchFiles0002.txt, etc.) , each with 650,000 lines, tab-delimited data.
I have a pattern file, with about 1000 lines with a single word. Each single word is found in the 1300 files once.
If I grep -f PatternFile.txt SearchFiles*.txt >OutputFile.txt... (2 Replies)
Hi Ladies and Gents,
Explanation of my question with an example:
Let's consider the script: backup_every_hour.sh
#!/bin/bash
rsync -auv $dir $backup_dir >> backup_every_hour_script.log
Each time this script is called there will be a new entry at the end of the file... (1 Reply)

Hello,
I want to grep a log ("server.log") for words in a separate file ("white-list.txt") and generate a separate log file containing each line that uses a word from the "white-list.txt" file.
Putting that in bullet points:
Search through "server.log" for lines that contain any word... (15 Replies)
Hello friends, I have a question.
Sometimes I have to search for an entry in a file that is repeated thousands of times. Can you tell me how to search so that i get limited results?
For example:
file: myfile.txt
grep "hello world" myfile.txt
this above grep will generate 5000... (4 Replies)
Hi there
I am trying to write a script where I will need to look for a specific word in the log file and I am aware this can be done by grep for example.
As there will be multiple entries for this I want to grep the last one to enter the log... how would I go about this - would I have to use... (5 Replies)
Hi,
I want to monitor a log file using tail -f command and search for a specific string on the most recent entry from the file. If the search string matches with the most recent or last line from the file, I want send an email to the people with the message.
tail -f service.log|tail -n 1

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
$
