# How to add bash dependencies to an electron#

In this section, we show the required steps to specify a list of bash dependencies in an electron. First, we import covalent.

[1]:

import covalent as ct


Next, we pass in the list of comma-separated bash commands as an argument to DepsBash()

[2]:

@ct.electron(
deps_bash=ct.DepsBash(["echo $PATH >> /tmp/path.txt"]), ) def get_bash_result(): with open('/tmp/path.txt','r') as f: return f.read()  We can also specify list of bash commands in the electron in implicit form. [3]:  @ct.electron( deps_bash=["echo$PATH >> /tmp/path.txt"],
)
def get_bash_result():
with open('/tmp/path.txt','r') as f:
