Yes, it’s the backslash.
To workaround it, use an -l switch to specify the username.
pscp -l PEM\username C:\Users\username\Desktop\list.txt 10.120.43.78:/home/local/PEM/username
Background:
The PSCP looks for the first colon, slash or backslash in the target. Only if the first symbol is colon, it considers the target as remote, otherwise as local.
/*
* Find a colon in str and return a pointer to the colon.
* This is used to separate hostname from filename.
*/
static char *colon(char *str)
{
/* We ignore a leading colon, since the hostname cannot be
empty. We also ignore a colon as second character because
of filenames like f:myfile.txt. */
if (str[0] == '\0' || str[0] == ':' ||
(str[0] != '[' && str[1] == ':'))
return (NULL);
str += host_strcspn(str, ":/\\");
if (*str == ':')
return (str);
else
return (NULL);
