 find . -xdev -type f -size +1024 -ls | awk '{print $11, $7}' | sort -rn +1 | awk '{print $1, $2/1024/1024 "MB"}'

 Check core files:

 find . -xdev -name core -exec ls -l {} \;

 List and remove the modified file

find . -xdev -mtime +60 -exec ls -l {} \;

 find . -xdev -mtime +60 -exec rm -rf {} \;

 Check disk usage:

 du -sk * |sort -n

 du -kx .| sort -n 

 du -sxk * | sort -nb | tail

 du -sk * | sort -nb | tail 

 du -sk *

 du -sk ./* 

 du -sk .
