tlmgr search

Search for TeX Live packages using (Perl) regular expressions. More information: https://www.tug.org/texlive/tlmgr.html.

• Search for a package name and descriptions of all locally installed packages from a specific regular expression:
  tlmgr search "{{regular_expression}}"
• Search for all file names of all locally installed packages from a regular expression:
  tlmgr search --file "{{regular_expression}}"
• Search for all file names, package names, and descriptions of all locally installed packages from a regular expression:
  tlmgr search --all "{{regular_expression}}"
• Search the TeX Live database, instead of the local installation:
  tlmgr search --global "{{regular_expression}}"
• Restrict the matches for package names and descriptions (but not for file names) to whole words:
  tlmgr search --all --word "{{regular_expression}}"
