-size n[cwbkMG]
File uses n units of space. The following suffixes can be used:
'b' for 512-byte blocks (this is the default if no suffix is used)
#這是預設單位，如果單位為b或不寫單位，則按照 512Byte搜尋
'c' for bytes
#搜尋單位是c，按照位元組搜尋
'w' for two-byte words
#搜尋單位是w，按照雙位元組（中文）搜尋
'k'for Kilobytes (units of 1024 bytes)
#按照KB單位搜尋，必須是小寫的k
'M' for Megabytes (units of 1048576 bytes)
#按照MB單位搜尋，必須是大寫的M
'G' for Gigabytes (units of 1073741824 bytes)
#按照GB單位搜尋，必須是大寫的G

也就是說如果要按照位元組來進行搜尋，則需要加上“c”

[[email protected] ~]# find.-size 1207c
./anaconda-ks.cfg
#使用搜索單位c，才會按照位元組搜尋
