In Powershell 5 escaping double quotes can be done by backtick      But sometimes you need to provide your double quotes escaped which can be done by backslash   backtick       Eg in this curl call  C  Windows System32 curl exe -s -k -H  quot Content-Type  application json quot  -XPOST localhost 9200 index name inded type -d quot     quot velocity   quot  3 14  quot

Escaping parameters like that is usually source of frustration and feels a lot like a time wasted  I see you re on v2 so I would suggest using a technique that Joel  Jaykul  Bennet blogged about a while ago   Long story short  you just wrap your string with               Start-Process   server toto exe    -batch B -param  sort1 parmtxt  Security ID 1234         Mind that I assumed which quotes are needed  and which things you were attempting to escape   If you want to work with the output  you may want to add the -NoNewWindow switch   BTW  this was so important issue that since v3 you can use --  to stop the PowerShell parser from doing anything with your parameters     server toto exe --  -batch b -param  sort1 paramtxt  Security ID 1234         should work fine there  with the same assumption

I found myself in a similar predicament today while trying to run a command through a Node js module   I was using the PowerShell and trying to run   command -e  func  a     But with the extra symbols  PowerShell was mangling the arguments  To fix  I back-tick escaped double-quote marks   command -e   func  a

Using the backtick     works fine for me if I put them in the following places    cmd    server toto exe -batch B -param   sort1 parmtxt  Security ID 1234        cmd returns as     server toto exe -batch B -param  sort1 parmtxt  Security ID 1234     Is that what you were looking for   The error PowerShell gave me referred to an unexpected token  sort1   and that s how I determined where to put the backticks   The           syntax is called a  here string  and will return exactly what is entered  You can also use them to populate variables in the following fashion    cmd       server toto exe -batch B -param  sort1 parmtxt  Security ID 1234         The opening and closing symbols must be on their own line as shown above
