w

[address1 [, address2 ]]w file

Append contents of pattern space to file . This action occurs when the command is encountered rather than when the pattern space is output. Exactly one space must separate the w and the filename. A maximum of 10 different files can be opened in a script. This command creates the file if it does not exist; if the file exists, its contents are overwritten each time the script is executed. Multiple write commands that direct output to the same file append to the end of the file.

Example

# Store tbl and eqn blocks in a file:
/^\.TS/,/^\.TE/w troff_stuff
/^\.EQ/,/^\.EN/w troff_stuff
