Re: Facing problem with perl one-liner for single quote

I am trying a one-liner substitution for a content in
a file.

original file content
---------
signal TCLK_IN : std_logic;
signal TPOS_IN : std_logic; ---------

I want to change it as:
---------
signal TCLK_IN : std_logic;
signal TPOS_IN : std_logic := '0';
-------

I wrote this one liner,

perl -pi -e 's/signal TPOS_IN \: std_logic;/signal
TPOS_IN \: std_logic \:= \'0\';/' <file_name>

But here i get an error saying, "Unmatched single
quote".

Use double-quotes instead, at least if you are on Windows.

perl -pi"orig_*" -e "s/(TPOS_IN[^;]+)/$1 := '0'/" <file_name>
