Git relative

Merge specific files from another branch

Says merge branch_B's specific files or directories to branch_A

git checkout branch_A
git checkout branch_B -- path_to_files_or_dirs

Inspect and delete remote branch

git branch -r
git push <remote-name> --delete <branch-name>
git fetch origin --prune #This option tells Git to remove any remote-tracking references in your local repository that no longer exist on the remote. In other words, if a branch has been deleted on the remote, --prune will remove the corresponding reference from your local repository.

Branch rename

if on the branch that want to rename:

git branch -m <new_branch_name>

else:

git branch -m <old_branch_name> <new_branch_name>

Discard changes in branch

git restore <branch-name>

# compress
tar cvzf cmprssd.tar.gz cmprssd/

REF: tar-extract-linux

To unpack or extract a tar file, type:

tar -xvf file.tar

To save disk space and bandwidth over the network all files are saved using compression program such as gzip or bzip2. To extract / unpack a .tar.gz (gzip) file, enter (note -z option):

tar -xzvf file.tar.gz

To extract / unpack a .tar.bz2 (bzip2) file, enter (note -j option):

tar -xjvf file.tar.bz2

To extract .rar

sudo apt install unrar
unrar x file.rar

chmod(change to user permission)

sudo chmod -R 777 "target_dir_name"
