How to Find Large Files in Ubuntu Linux

kb-admin — Wed, 25 May 2011 19:59:01 +0000

If you want to find files above a certain size, or find files between certain sizes, then you may use the +size x and -size x switches to the find command.

For example:

find /etc -size +100k -size -150k

This command will find all files inside the /etc directory that are between 100k and 150k in size.

How to Make a Backup Script for Shell in Linux

kb-admin — Wed, 14 Apr 2010 02:47:18 +0000

For those who hack a lot of Linux at the command line interface, backing up files such as config files before editing is a good habit to have. IMHO anyway. So to save time, a little script can be written, chmod +x, and placed into /usr/local/bin or some other that users have in their executable shell PATH. I name mine “bu” to make it easy, and it takes one command line argument which is the filename of the file you want to make a backup copy of. It is called by running something like $ bu myfile

Here’s the code. Comments welcome ;) The code creates a timecode based on today’s date and the current time to the second, and appends that to the original filename. The a copy is saved with this new “timestamped” backup filename, right in the same directory. Easy-peasy!

#!/bin/bash
OLDFILENAME=$1
DATECODE=$(date +%Y%m%d)
TIMECODE=$(date +%H%M%S)
NEWFILENAME="${OLDFILENAME}_backup${DATECODE}-$TIMECODE"
cp $OLDFILENAME $NEWFILENAME
SUCCESS=$?
if [ $SUCCESS -eq 0 ];then
 echo "OK! Copied \"$OLDFILENAME\" to \"$NEWFILENAME\""
else
 echo "FAIL! You'll need to try again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
fi
