Sintaksis Sed

$ sed 'ADDRESSs/REGEXP/REPLACEMENT/FLAGS' nama_berkas
$ sed 'PATTERNs/REGEXP/REPLACEMENT/FLAGS' nama_berkas
# s is substitute command # / is a delimiter # REGEXP is regular expression to match # REPLACEMENT is a value to replace
FLAGS can be any of the following # g Replace all the instance of REGEXP with REPLACEMENT # n Could be any number,replace nth instance of the REGEXP with REPLACEMENT. # p If substitution was made, then prints the new pattern space. # i match REGEXP in a case-insensitive manner. # w file If substitution was made, write out the result to the given file. # We can use different delimiters ( one of @ % ; : ) instead of /
  • Tambahkan kata "CASCADE" untuk setiap baris yg diawali oleh kata "DROP" dan diakhiri karakter ";"
Isi file drop.sql
DROP TABLE petruk_line_produksi;

DROP TABLE petruk_status_mutasi;
DROP TABLE petruk_statusnc;
CREATE TABLE gareng_stat ....;
DROP TABLE petruk_tindakannc;
$ sed -i '/^DROP/s/;$/ CASCADE;/' mytable.sql
Output DROP TABLE petruk_line_produksi CASCADE; DROP TABLE petruk_kapasitas_produksi CASCADE; DROP TABLE petruk_status_mutasi CASCADE; DROP TABLE petruk_statusnc CASCADE; DROP TABLE petruk_tindakannc CASCADE;
