mktemp-d

Never create a temporary file or directory at a hardcoded path under /tmp. Always allocate a private directory with mktemp -d and place all temporary artifacts inside it.

Why

mktemp -d returns a unique, private directory. A hardcoded path under /tmp does not — it collides with concurrent runs and any leftover state from prior runs.

Rule

One mktemp -d per logical scope, then build paths inside it:

tmpdir=$(mktemp -d)

cp something "$tmpdir/input"
do_work > "$tmpdir/output.log"

Direct substitutions

Don't	Do
`mkdir /tmp/work`	`work=$(mktemp -d)`
`touch /tmp/out.log`	`work=$(mktemp -d); : > "$work/out.log"`
`cmd > /tmp/output`	`work=$(mktemp -d); cmd > "$work/output"`
`tar xf x.tar -C /tmp`	`work=$(mktemp -d); tar xf x.tar -C "$work"`

If you encounter a hardcoded /tmp/... path while editing a file, replace it with the mktemp -d idiom as part of the same edit.
