Sends log lines from murmur's (the mumble server's) logfile to syslog.

Watches for file modifications in the current directory and tails the file.

this also can find the old command you used before

I know how hard it is to find an old command running through all the files because you couldn't remember for your life what it was. Heres the solution!! Grep the history for it. depending on how old the command you can head or tail or if you wanted to search all because you cannot think how long ago it was then miss out the middle part of the command. This is a very easy and effective way to find that command you are looking for.

zsh: list of files sorted by size, greater than 100mb, head the top 5. '**/*' is recursive, and the glob qualifiers provide '.' = regular file, 'L' size, which is followed by 'm' = 'megabyte', and finally '+100' = a value of 100

On the Mac, the 'ls' function can sort based on month/day/time, but seems to lack ability to filter on the Year field (#9 among the long listed fields). The sorted list continuously increases the 'START' year for the most recently accessed set of files. The final month printed will be the highest month that appeared in that START year. The command does its magic on the current directory, and suitably discards all entries that are themselves directories. If you expect files dating prior to 2002, change the START year accordingly.

This one is tried and tested for Ubuntu 12.04. Works great for tailing any file over http.

Used in OS X.

tr "\n" ";"

may be replaced by

echo ";"

with linux versions of date.

I reused

ping -q -c 1 www.google.com|tail -1|cut -d/ -f5

You can simply run "largest", and list the top 10 files/directories in ./, or you can pass two parameters, the first being the directory, the 2nd being the limit of files to display.

Best off putting this in your bashrc or bash_profile file

count & sort one field of the log files , such as nginx/apache access log files .

'newfile' will have content of 'file' minus first 55 lines

to delete first line only do:

tail +2 file > newfile

without reverse...

will check if the last byte of filename is a unix newline character. tail -c1 yields the file's last byte and xxd converts it to hex format.

Output lines starting at line 2.

more variety
