Lookup C Documentation
Recently discovered there is a way to jump to the libc manual (if installed) for a given function. Could potentially work with other languages with info reference manuals, if there are any.
- 'C-h S' info-lookup-symbol
Display the definition of SYMBOL, as found in the relevant manual. When this command is called interactively, it reads SYMBOL from the minibuffer. In the minibuffer, use M-n to yank the default argument value into the minibuffer so you can edit it. The default symbol is the one found at point.
Nice in conjunction with 'M-x man' which I have bound to 'C-x m'.
Convert between binary and decimal in calc
- type 'd2' to binary
- type 'd6' to hexadecimal
- type 'd0' to decimal
These only change how numbers are displayed, input numbers are still read in decimal.
To input numbers in the current base type '#'.
Recursively sync directory with FTP
lftp -e "mirror -R [source [target]]" -u [username],[password] [host]
-R means reverse, because the mirror command normally works from server to
lftp's mirror command has a wide breadth of options that can be used to fit your needs. In my case I was trying to replicate rsync style syncing for a system that I only had FTP access to.
