You don't need to analyze the logfile at all to quit when scp fails. Every program has an exit status, 0 for success, anything else for some sort of error. You can tell it to quit when scp returns nonzero by:

Code:

/bin/scp -v you@example.com || exit 1

If you want to be more specific about the error conditions, scp appears to return different error codes for different errors:

Code:

SCP Return Codes
0	Operation was successful
1	General error in file copy
2	Destination is not directory, but it should be
3	Maximum symlink level exceeded
4	Connecting to host failed.
5	Connection broken
6	File does not exist
7	No permission to access file.
8	General error in sftp protocol
9	File transfer protocol mismatch
10	No file matches a given criteria
65	Host not allowed to connect
66	General error in ssh protocol
67	Key exchange failed
68	Reserved
69	MAC error
70	Compression error
71	Service not available
72	Protocol version not supported
73	Host key not verifiable
74	Connection failed
75	Disconnected by application
76	Too many connections
77	Authentication cancelled by user
78	No more authentication methods available
79	Invalid user name

So:

Code:

/bin/scp -v you@example.com
# There must be no statements between this assignment and the scp call!
SCPSTATUS="$?"

if [ "$SCPSTATUS" -ne 0 ]
then
        echo "SCP quit with status $SCPSTATUS"
        exit 1
fi

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern

SYNOPSIS

       #include <tcl.h>

       int
       Tcl_StringMatch(str, pattern)

       int
       Tcl_StringCaseMatch(str, pattern, flags)

ARGUMENTS

       const char *str (in)		 String to test.

       const char *pattern (in) 	 Pattern to match against string.  May contain special characters from the set *?[].

       int flags (in)			 OR-ed combination of match flags, currently only TCL_MATCH_NOCASE.  0 specifies a case-sensitive search.
_________________________________________________________________

DESCRIPTION

       This  utility  procedure  determines  whether  a  string  matches  a given pattern.  If it does, then Tcl_StringMatch returns 1.  Otherwise
       Tcl_StringMatch returns 0.  The algorithm used for matching is the same algorithm used in the string match Tcl command and  is  similar	to
       the algorithm used by the C-shell for file name matching;  see the Tcl manual entry for details.

       In  Tcl_StringCaseMatch,  the algorithm is the same, but you have the option to make the matching case-insensitive.  If you choose this (by
       passing TCL_MATCH_NOCASE), then the string and pattern are essentially matched in the lower case.
