The syntax for the search command: search [-s start | -k | -u] [-e end | -l length] [-m mask] value ... allows multiple values for simultaneous search. For example: crash-5.1.1str> search -k 00007ffffd401e28 00007f29a0cbeb9f ffff88011e889f70: 7ffffd401e28 ffff88011e889fd8: 7f29a0cbeb9f I thought I'd use a similar syntax for strings (-c for "chars", looking for a better letter, maybe -S): crash-5.1.1str> search -k -c "Memory value expected" "No such file or" The current version of parse_line in tools.c has a problem with repeated strings, so that it delivers the following in the value[] array: (gdb) p value[0] $1 = 0xb74a04 "Memory value expected" (gdb) p value[1] $2 = 0xb74a1b "\"No" (gdb) p value[2] $3 = 0xb74a1f "such" (gdb) p value[3] $4 = 0xb74a24 "file" (gdb) p value[4] $5 = 0xb74a29 "or\"" With the attached patch, it delivers: (gdb) p value[0] $1 = 0xb77a24 "Memory value expected" (gdb) p value[1] $2 = 0xb77a3c "No such file or" I don't think it messes anything else up...
