find -name '*filename*'
This command allows you to search files but it will search only current directory as recursive. So, for entire system search you should be in the bottom directory.
Using this command will give you size of a folder:
“du -ms folder/”
For learning size of a file
“du -m file.txt”
m for megabytes
You can use tar:
“tar -zcvf archive.tar.gz folder/”
-z: Compress with gzip
-c: Create archive
-v: Display progress
For extracting archive:
“tar -zxvf archive.tar.gz -C /extractionpoint”
|-C Directory||Causes the tar command to perform a chdir subroutine to the directory specified by the Directory variable. Using the -C flag allows multiple directories not related by a close common parent to be archived, using short relative path names. For example, to archive files from the /usr/include and /etc directories, you might use the following command:
tar c -C
