To manage temporary files in Linux, a Bash script can move files untouched for 10 days to a timestamped subfolder, return modified files to the root, and delete files not modified for 90 days. Alternatively, a folder with symlinks to recently accessed files can be created using mkdir, find with -atime -7 to locate recently accessed files, and a while loop with ln -s to symlink each file into the folder. Both approaches help organize files based on access time to avoid clutter and remove stale temporary files. The Bash script offers more automation while the symlink folder provides a manual way to access recent files.

#!/bin/sh
# Select a file with fzf from a database sorted by frecency and open it using
# xdg-open. frece can be found at https://github.com/YodaEmbedding/frece

DB_FILE=${FRECE_FILES_DB:-$HOME/.cache/frecent-files.csv}
item=$(frece print "$DB_FILE" | fzf --tiebreak=index --scheme=path)

[ -z "$item" ] && exit 1
frece increment "$DB_FILE" "$item"

xdg-open "$item"

#!/bin/sh
# Update frece database

DB_FILE=${FRECE_FILES_DB:-$HOME/.cache/frecent-files.csv}
tmp_file=$(mktemp)
fd -H . ~ > "$tmp_file"  # use ~/.fdignore file to exclude certain dirs
frece update "$DB_FILE" "$tmp_file" --purge-old
rm "$tmp_file"
