Using the shell

Helpful shell commands

• ssh kitzeslab@<robin's URL>
• pwd - print working directory. This is the directory, aka the "folder", that you're issuing commands from.
• ls - list contents of the current working directory
• ls /Volumes/seagate1/ - list the contents of the directory /Volumes/seagate1/
• ls -lh - list the files with more information: l = long list, h = human-readable file sizes
• cd - change directories into your home directory
• cd .. - go up one directory, e.g. from /Volumes/seagate1/ to /Volumes/.
• cd seagate1/ - change directories into seagate1/. This is a relative path, i.e. the shell attempts to change into a directory contained within the current working directory.
• cd /Volumes/seagate1 - change directories into /Volumes/seagate1/. This is an absolute path, i.e. you can do this from any working directory
• mkdir hello - make a directory called hello within the current directory
• mkdir /Users/tessa/Recordings/MSD-0001 - make the directory MSD-0001 within preexisting directory /Users/tessa/Recordings/.
• scp kitzeslab@<robin's URL>:/Volumes/seagate1/data/field-data/<date folder>/<card folder>/<filename>.WAV . - copy a file into your current working directory (specified by .).
• scp kitzeslab@<robin's URL>:/Volumes/seagate1/data/field-data/<date folder>/<card folder>/<filename>.WAV /Users/<username>/Recordings - copy a file into the directory /Users/<username>/Recordings.
