# # This is necessary because, if `grep ...` doesn't find anything, it will _return_ (not print) a value of 1
|
|
# # (non-zero return codes indicating errors in Unix - since there are many more ways for something to go wrong
|
|
# # than there are for it to go right!), and so the `files=` assignment will also return 1, and the whole operation
|
|
# # will be considered a failure.
|
|
# #
|
|
# # Since a non-zero value is truthy in Linux, we can use the OR operator (`||`) to only execute the second command
|
|
# # if the first one errors out. So, this line can be translated to English as:
|
|
# # "Set the variable `files` to a list of all the files that contain `TK` - unless there aren't any, in which case
|
|
# # set it to `FILES NOT FOUND"
|
|
# - files=$(grep -rl 'TK' blog/content/posts || echo "FILES NOT FOUND")
|
|
# # We have to filter out (`grep -v`) the "marker" value of `FILES NOT FOUND`, otherwise the no-matches case would
|
|
# # be recorded as having 1 matching file, leading to an error-out below.
|
|
# # (I guess _technically_ there's an edge case in that, if I ever make a blog post titled "FILES NOT FOUND" _which also_
|
|
# # contains the string `TK`, it would slip through this check. But that feels pretty unlikely - not least because spaces
|
|
# # are very rare in my filesystem names - so I'm ok taking that risk)
