I would like to append the following to my ~/.bash_profile:

# ---------------
# PERSONNAL EDITS

# anaconda3
. /opt/anaconda3/etc/profile.d/conda.sh

To do so, I use the script:

#!/bin/bash

app_str=\
'\n
# ---------------\n
# PERSONNAL EDITS\n
\n
# anaconda3\n
. /opt/anaconda3/etc/profile.d/conda.sh'

echo -e $app_str >> ~/.bash_profile

However, the result is the following:

<lines above...>

 # ---------------
 # PERSONNAL EDITS 

 # anaconda3
 . /opt/anaconda3/etc/profile.d/conda.sh

There is a spacing in front of each line appended to the file. How do I remove the spacing?

Quote the variable:

echo -e "$app_str"

  • Hi thanks for the answer, could you elaborate what the double quote does? Commented Jan 2, 2020 at 14:41

I'd suggest using a here document instead:

cat >> ~/.bash_profile <<'EOF'    
# ---------------
# PERSONNAL EDITS

# anaconda3
. /opt/anaconda3/etc/profile.d/conda.sh
EOF

IMHO it's easier to read and more maintainable than trying to echo a multiline string.
