Install 7zip on Ubuntu:
sudo apt-get install p7zip-full
Check if 7zip is installed properly:
7z
To see a list of all files and folders in the current directory
ls -la
Create a compressed file named data.7z using the command
7z a data.7z data.txt
To create a compressed file with the contents of a directory, first cd into that directory (e.g. NameOfDirectory) and use the following command to generate a NameOfDirectory.7z file:
7z a -r NameOfDirectory
Extract a .7z compressed file:
7z e data.7z

Copy a directory/folder from local system to a remote system via SSH:
#CD into the directory on the local system
#-q tag is for making it silent so that you do not see the names of the files being copied on the terminal
scp -r -q SourceFolderName/ userNameOnRemoteSystem@XXX.XX.X.X:/home/user/destDirectory
Browse files on another ubuntu system from client ubuntu system:
Find the size of a directory: du -sh dirname/
Tail like command for windows using Windows Powershell to extract last few lines of a large text file:
Get-Content "inputfile.txt" -Wait -Tail 3000 > tail.txt
Useful Linux Navigating Commands
Zip a folder (and exclude a sub-folder)
zip -r myarchive.zip dir1 -x dir1/ignoreDir1/**\* dir1/ignoreDir2/**\*
-
To remove a folder with all its contents (including all interior folders):
rm -rf /path/to/directory -
To remove all the contents of the folder (including all interior folders) but not the folder itself:
rm -rf /path/to/directory/*or, if you want to make sure that hidden files/directories are also removed:
rm -rf /path/to/directory/{*,.*} -
To remove all the "files" from inside a folder(not removing interior folders):
rm -f /path/to/directory/{*,.*}
Warning: if you have spaces in your path, make sure to always use quotes.
rm -rf /path/to the/directory/*
is equivalent to 2 separate rm -rf calls:
rm -rf /path/to
rm -rf the/directory/*
To avoid this issue, you can use 'single-quotes'(prevents all expansions, even of shell variables) or "double-quotes"(allows expansion of shell variables, but prevents other expansions):
rm -rf "/path/to the/directory/"*
Where:
rm- stands for remove-f- stands for force which is helpful when you don't want to be asked/prompted if you want to remove an archive, for example.-r- stands for recursive which means that you want to go recursively down every folder and remove everything.
