"var = $(

Question

I am a beginner with bash scripts and my bash script begins with reading a file's one line content into a variable, however it returns the error

pid: not found

My script looks like:

pid = `cat /home/file.py`
echo $pid

I also tried

pid = $(</home/file.py)

and got the same error.

BTW, http://shellcheck.net/ would have found this for you without needing to get any humans involved. — Charles Duffy, Jul 08 '15 at 16:23
With the title adjusted (which will further help searchability), I think this is now no longer a good choice for close-as-typo, and now a good choice for a dupe close, making it a guidepost for the better-asked question. — Charles Duffy, Jul 08 '15 at 18:08
http://stackoverflow.com/questions/2459286/unable-to-set-variables-in-bash-script/2459863#2459863 is a better one. — Charles Duffy, Jul 08 '15 at 18:11

In pid = $(</home/file.py), = and $(</home/file.py) is arguments for a command pid. It doesn't specify an assignment. For assignment you need to do:

var=something #without any space in-between
