Change directory

SHBash & Linux

Change Directory

syntax

cd [directory]

example

cd /var/log
cd ~
cd ..
cd -

Note cd with no argument returns to your home directory. cd - switches to the previous directory you were in, which is great for toggling between two locations.

WORKDIR — Set Working Directory

DK · Dockerfile

syntax

WORKDIR /path/to/dir

example

WORKDIR /app
COPY . .
RUN npm ci

Note All subsequent RUN, CMD, COPY, and ENTRYPOINT instructions use this directory. WORKDIR creates the directory if it does not exist. Avoid using RUN cd /app — it only affects that single RUN layer.
