Sometimes you want to find a keyword backwards. This is, before the current offset, to do this you can seek back and search forward by adding some search.from/to restrictions, or use the `/b` command.
[0x100001200]> / nop 0x100004b15 hit0_0 .STUWabcdefghiklmnopqrstuvwxbin/ls. 0x100004f50 hit0_1 .STUWabcdefghiklmnopqrstuwx1] [file . [0x100001200]> /b nop [0x100001200]> s 0x100004f50p [0x100004f50]> /b nop 0x100004b15 hit2_0 .STUWabcdefghiklmnopqrstuvwxbin/ls. [0x100004f50]>
Note that `/b` is doing the same as `/`, but backward, so what if we want to use `/x` backward? We can use `/bx`, and the same goes for other search subcommands:
