Usage: ${1##*/} [OPTIONS] PACKAGES
|
|
${1##*/} -a [OPTIONS]
|
|
|
|
Display package sizes. Duplicates are removed if any. Output can be sorted by
|
|
name or size. A grand total can be printed at the end. Both the sync and the
|
|
local databes can be used for lookup.
|
|
|
|
Options:
|
|
|
|
-a: All installed packages. Implies -Q.
|
|
-h: Show this help.
|
|
-n: Output is sorted by name.
|
|
-Q: Use local database. It speeds up queries and allows displaying
|
|
size of local packages not available in repos.
|
|
-S: Use sync database. It is slower but allows to display size of
|
|
non-installed packages.
|
|
-s: Output is sorted by size.
|
|
-t: Print total.
|
|
|
|
Examples:
|
|
|
|
${1##*/} -ast
|
|
Convenient way to keep track of big packages.
|
|
|
|
${1##*/} -Q \$(pactree -ld1 linux)
|
|
Print the size of linux and all its direct dependencies.
|
|
|
|
${1##*/} -Qst \$(pacman -Qdtq)
|
|
Print a grand total of orphan packages, and sort by size.
