Error in Perl oneline command

perl -pi -e 's|\x20|; s|\x90|' log.bin

gives me this error

Backslash found where operator expected at -e line 1, near "s|\x20|; s|\"
syntax error at -e line 1, near "s|\x20|; s|\"
Execution of -e aborted due to compilation errors.

What am I doing wrong? the line intended to replace all bytes with 0x20 to 0x90...

You have 2 half statements, instead of one complete one. You're probably looking for

perl -pi -e 's|\x20|\x90|g' log.bin

You formatted the s command wrong. Try this:

s|\x20|\x90|g;

The g means global and the formatting is necessary for the command

you have two incomplete substitutions in that command, you say substitute \x20 without specifying what it should be replaced with, then separately say replace \x90 again omitting the replacement. This is a syntax error.

the correct syntax is

s|\x20|\x90|g ;
