According to my Cygwin setup program "setup-x86_64.exe", I have package texlive-collection-latexextra version 20220321-1. The Cygwin package search page says that this package should contain usr/share/texmf-dist/tex/latex/changes/changes.sty, whch I confirmed.
The output from cygcheck --help says that cygcheck -f FILE [FILE]... will "find the package to which FILE belongs". However, cygcheck -f changes.sty returns nothing.
What am I doing wrong?
It turns out that you need to specify the full path of the file:
# Nothing gets listed
cygcheck -f changes.sty
Nothing gets listed
cygcheck -f
usr/share/texmf-dist/tex/latex/changes/changes.sty
Package is listed
cygcheck -f
/usr/share/texmf-dist/tex/latex/changes/changes.sty
texlive-collection-latexextra-20220321-1
I have the following as the script /usr/local/bin/cygsearch (with /usr/local/bin in my $PATH, obviously)
#!/bin/sh
#
if [ $# -eq 0 ]
then
echo "Usage: ${0##*/} <program_name>" >&2
exit 1
fi
cygcheck -p "/$1"
This version uses an online repository search for the specified file, returning a list of packages where there is a match. For example,
cygsearch date.exe
Found 6 matches for /date.exe
coreutils-debuginfo-8.26-2 - coreutils-debuginfo: Debug info for coreutils
coreutils-debuginfo-8.32-1 - coreutils-debuginfo: Debug info for coreutils
coreutils-debuginfo-9.0-1 - coreutils-debuginfo: Debug info for coreutils
coreutils-8.26-2 - coreutils: GNU core utilities (includes fileutils, sh-utils and textutils)
coreutils-8.32-1 - coreutils: GNU core utilities (includes fileutils, sh-utils and textutils)
coreutils-9.0-1 - coreutils: GNU core utilities (includes fileutils, sh-utils and textutils)
You don't always need to include the .exe suffix, but without it I find I often get too many false positives for the results I'm expecting
