"stray \ before !" in script

[szigetva]

I got the error message .grep: warning: stray \ before ! when bb ran. I changed \! to ! in two lines in the script, which fixed the error.

Here's the diff:

710c710 < nposts=$(grep -c "<\!-- text begin -->" "$i") --- > nposts=$(grep -c "<‍!-- text begin -->" "$i") 870c870 < nposts=$(grep -c "<\!-- text begin -->" "$i") --- > nposts=$(grep -c "<‍!-- text begin -->" "$i")

Note that I had to add a zero-width space in the code above so that it renders properly, I guess you can't just copy it as is.

With this modification the footer is inserted twice. The issue remains, my solution above is not adequate.

redirect stderr from grep command to /dev/null by changing the line as follows:

nposts=$(grep -c "<‍!-- text begin -->" "$i" 2>/dev/null)
