NAME
kpsewhich - standalone path lookup and and expansion for kpathsea SYNOPSIS
kpsewhich [options] [filenames] DESCRIPTION
This manual page is not meant to be exhaustive. The complete documentation for this version of TeX can be found in the info file or manual Kpathsea: A library for path searching. kpsewhich is used as a standalone front-end of the kpathsea library that can be used to examine variables and find files. When the -format option is not given, the search path used when looking for a file is inferred from the name given, by looking for a known extension. If no known extension is found, the search path for TeX source files is used. OPTIONS
kpsewhich accepts the following options: -debug num Set debugging flags. -D num Use a base resolution of num; the default, set by the installer, is typically 600. -dpi num As -D. -engine string Set $engine in the environment, which is used in some search paths. -expand-braces string Print variable and brace expansion of string. -expand-path string Print complete path expansion of string. -expand-var string Print variable expansion of string. -format name Use file type name. See the info manual for a list of valid names, or use the -help option to print the list. -help Print help message and exit. -interactive Ask for additional filenames to look up. -mktex fmt enable mktexfmt generation. (fmt=pk/mf/tex/tfm) -mode string Set device name for $MAKETEX_MODE to string; no default. -must-exist Search the disk as well as ls-R if necessary. -no-mktex fmt disable mktexfmt generation. (fmt=pk/mf/tex/tfm) -path string Search in the path string. -progname string Set program name to string. -show-path name Output search path for file type name. See the info manual for a list of valid names, or use the -help option to print the list. -var-value variable Print the expansion of variable. -version Print version information and exit. SEE ALSO
