$> ./mod-elf-symbol -o main.o -s foo --singlestr=bar > /dev/zero

Replace symbol foo

foo --> bar

$> ./mod-elf-symbol -o main.o -c foo --completestr=bar > /dev/zero

Number symbol foo

foo --> foo__1

$> ./mod-elf-symbol -o main.o -k foo --keepnumstr=__ > /dev/zero 

Examples with Makefile

$> make <run_append | run_replace | run_number>  

TEMPLATES TO USE

Append to symbol(s):
foo --> foo<string_to_append>

$> ./mod-elf-symbol -o file1.o [more files.o ...] \
-s symbol1 symbol2 symbol3 [more symbols ...] \
--singlestr=<string_to_append>

Replace symbol(s):
foo --> <new_symbol>

$> ./mod-elf-symbol -o file1.o [more files.o ...] \
-c symbol1 [more symbols ...] \
--completestr=<new_symbol>

Number symbols(s):
foo --> foo<string_inbetween><number>

$> ./mod-elf-symbol -o file1.o [more files.o ...] \
-k symbol1 symbol2 symbol3 [more symbols ...] \
--keepnumstr=<string_inbetween>
