Multiple commands

sed

Source

• simply concatenate the commands with ;

  sed -n 's/\.//g;s/!define VERSION //p' "${0%/*}/setup.nsi"

• alternatively you could use multiple -e’s

  sed -n -e 's/\.//g' -e 's/!define VERSION //p' "${0%/*}/setup.nsi"

• the -n option causes sed to only output changed lines (in combination with the p command at the end)
