# cg\_merge(1)

(deprecated) merges multiple Cachegrind output files into one

## NAME

cg\_merge - (deprecated) merges multiple Cachegrind output files into one

## SYNOPSIS

**cg\_merge** \[*options*\] \[*cachegrind-out-files*...\]

## DESCRIPTION

**cg\_merge** sums together multiple Cachegrind output files into a single Cachegrind output file. It is deprecated because **cg\_annotate** can now do much the same thing, but better.

## OPTIONS

- **-o outfile**

  Write the output to to outfile instead of standard output.
