find_file

pyomo.common.fileutils.find_file(filename, cwd=True, mode=4, ext=None, pathlist=[], allow_pathlist_deep_references=True)[source]

Locate a file, given a set of search parameters

Parameters:

filename (str) – The file name to locate. The file name may contain references to a user’s home directory (~user), environment variables (${HOME}/bin), and shell wildcards (? and *); all of which will be expanded.
cwd (bool) – Start by looking in the current working directory [default: True]
mode (mask) – If not None, only return files that can be accessed for reading/writing/executing. Valid values are the inclusive OR of {os.R_OK, os.W_OK, os.X_OK} [default: os.R_OK]
ext (str or iterable of str) – If not None, also look for filename+ext [default: None]
pathlist (str or iterable of str) – A list of strings containing paths to search, each string contains a single path. If pathlist is a string, then it is first split using os.pathsep to generate the pathlist [default: []].
allow_pathlist_deep_references (bool) – If allow_pathlist_deep_references is True and the filename appears to be a relative path, allow deep reference matches relative to directories in the pathlist (e.g., if filename is foo/my.exe and /usr/bin is in the pathlist, then find_file() could return /usr/bin/foo/my.exe). If allow_pathlist_deep_references is False and the filename appears to be a relative path, then only matches relative to the current directory are allowed (assuming cwd==True). [default: True]

Notes

find_file uses glob, so the path and/or file name may contain wildcards. The first matching file is returned.
