I'm not very familiar with the ssh command. When I tried to set a variable and then echo its value on a remote machine via ssh, I found a problem. For example,
$ ITSME=itsme
$ ssh xxx.xxxx.xxx.xxx "ITSME=itsyou; echo $ITSME"
itsme
$ ssh xxx.xxxx.xxx.xxx 'ITSME=itsyou; echo $ITSME'

atexpand(3) AtFS Toolkit Library atexpand(3)NAME
atExpandAttrs, atExpand - attribute expansion
SYNOPSIS
#include <atfs.h>
#include <atfstk.h>
int atExpandAttrs (Af_key *aso, char *buf, size_t bufSize, FILE *dest, size_t destSize, int mode);
int atExpand;
DESCRIPTION
atExpandAttrs scans the char buffer buf to the extent of bufSize for strings of the form $__attributeName optionally followed by a delimit-
ing (second) dollar sign ($). If such a string is found, the buffer contents up to the character preceding the first dollar sign will be
sent to the destination output dest. If an attribute with name attributeName is set for the current attributed software object aso, the
citation-string will be substituted by the value of that attribute and appended to the output. Output of buf contents resumes with the
first character after the whitespace character or dollar sign delimiting attributeName.
Despite the type of the dest argument (pointer to file structure), atExpandAttrs may be caused to copy it's output to a string buffer
rather than an open file. In this case, the constant AT_EXPAND_STRING must be given as mode argument and bufSize must be set to indicate
the length of the destination buffer dest (will be casted to character pointer). If destSize is to small to hold the result string, atEx-
pandAttrs returns a negative value. In the regular case, where output shall be written to a file, the mode parameter must be
AT_EXPAND_FILE.
The atExpand variable suppresses attribute expansion when set FALSE. The variable may be set either directly from the application program
if indirectly by evaluation of the pseudo attribute citation $__xpoff in any buffer scanned by atExpandAttrs. Another pseudo attribute
citation $__xpon cancels the effect of a previous $__xpoff and switches attribute citation on again. It does not, however, enable attribute
citation if this was disabled explicitly by the application program.
DIAGNOSTICS
atExpandAttrs returns -1 on error. Additionally, the atError variable is set and afErrMsg holds a diagnostic message.
