How to avoid grep command finding commented out strings in the source file?

  • 772

I am running a software where I want to check if miniconda is already installed. Therefore I've checked whether 'miniconda' or 'anaconda' strings in .bashrc file using the grep command. However, it also finds either of above strings which are commented out in the .bashrc file, which I do not want to have. How do I fix this? Relevant part of my bashscript looks as follows.

#Finding if miniconda or anaconda string is in bashrc  
if grep -qF -e miniconda -e anaconda "$HOME"/.bashrc ;then    
  echo "miniconda is found in .bashrc"

I've tested this by adding following lines in the .bashrc file.

#anaconda
#miniconda

Terminal Output

jen@scs400:/scratch$ source bash_script.sh     
miniconda is found in .bashrc
scripts grep

    Try this:

    if grep -qwE '^[^#]*(ana|mini)conda' "$HOME"/.bashrc ;then
    echo "miniconda/anaconda is found in .bashrc"
fi
