openwrt 更新

升级可升级的所有包:

opkg update
opkg list-upgradable | cut -f 1 -d ' ' | xargs opkg upgrade

• List any available upgradable packages

opkg update
opkg list-upgradable

• Upgrade any packages listed (if any were listed) – more than one package can be included
  • Note: on a device with only 4MB of NVRAM, these updates may not fit – check free space on / first with “df -h /” and ensure there is at least 600KB or so free

opkg list-upgradable | sed -e "s/\s.*//" | while read PKG_NAME; do opkg upgrade "${PKG_NAME}"; done

• Verify no more packages can be upgraded; the command should display no output now

opkg list-upgradable

Reinstall user-installed packages

After a successful upgrade, you will need to reinstall all previously installed packages. You made a list of these above. Package configuration files should have been preserved due to steps above, but not the actual packages themselves.

• Restore pre-upgrade packages “automagically”

If you have used “sysupgrade -k” you should be able to run the following code to restore all packages (credits to rnio)

opkg update && opkg list-installed | cut -f 1 -d ' ' | sort -u > /tmp/currentpkg && cat /etc/backup/installed_packages.txt | cut -f 1 | sort -u > /tmp/oldpkg && grep -v -F -x -f /tmp/currentpkg /tmp/oldpkg > /tmp/inst && opkg install $(cat /tmp/inst | sort -u) && rm /tmp/currentpkg /tmp/oldpkg /tmp/inst

• Install packages manually

opkg update
opkg install snmpd-static
