cheat-sheet
My cheat sheet for commands I have trouble remembering.
Converting Emails
EML to MBOX using eml2mbox (email2mbox-git on AUR)
cd /path/to/eml/files
eml2mbox
This creates .archive.mbox.
MBOX to HTML Threads using Mhonarc (mhonarc on AUR)
cd /path/to/.archive.mbox/file
mhonarc .archive.mbox
This creates threads.html and extracts all information into the directory.
Find and copy files by extension recursively
find . -name '*.pdf' -exec cp -r {} /home/jpickard/pdffiles \;
7-Zip compression (p7zip)
7z a archivename.7z thingtobearchived
Recursively unzip
while [ "`find . -type f -name '*.zip' | wc -l`" -gt 0 ]; do find -type f -name "*.zip" -exec unzip -- '{}' \; -exec rm -- '{}' \;; done
Merge PDF files
Ghostscript
gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=mergedfile.pdf -dBATCH file1.pdf file2.pdf
