Description
Currently, (as of 3.17.0) printfile bodies can be used to report the contents of a file from the top of the file, but there is not yet a way of printing the last several lines of a file. For example:
bundle agent example_printfile(file)
{
reports:
"The first two lines of '$(file)':"
printfile => head_n( $(file), 2 );
"The full content of '$(file)'"
printfile => cat( $(file) );
}
bundle agent __main__
{
methods:
"Print Self"
usebundle => example_printfile($(this.promise_filename));
}
Outputs:
R: The first two lines of '/home/nickanderson/org/cfengine3-gPoHAy':
R: body file control{ inputs => { '$(sys.libdir)/stdlib.cf' };}
R: bundle agent example_printfile(file)
R: The full content of '/home/nickanderson/org/cfengine3-gPoHAy'
R: body file control{ inputs => { '$(sys.libdir)/stdlib.cf' };}
R: bundle agent example_printfile(file)
R: {
R: reports:
R: "The first two lines of '$(file)':"
R: printfile => head_n( $(file), 2 );
R:
R: "The full content of '$(file)'"
R: printfile => cat( $(file) );
R: }
R: bundle agent __main__
R: {
R: methods:
R: "Print Self"
R: usebundle => example_printfile($(this.promise_filename));
R: }
It would be nice if I could specify number_of_lines as a negative number, to print the end of the file, or perhaps a new body attribute to select a number of lines from the start or the end of the file.
