There is pdfunite (part of poppler) Linux package and pdfjam part of pdfpages (on debian there is separate pdfjam package).
Here are some comparison between the (pdfunite, pdfjam and pdftk) in speed, created file-size, support of PDF hyperlinks etc.:

If you need to reduce generated PDF file size with GS the common way is with:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf
Its also possible to merge PDF files by using simply Ghostscript (useful for older Linux releases and UNIX – Sun OS / Solaris / HP-UX etc.)
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged-file.pdf file1-to-merge.pdf file2-to-merge.pdf file3-to-merge.pdf

Install and configure rkhunter for improved security on a PCI DSS Linux / BSD servers with no access to Internet
–rwo, –report-warnings-only
This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
be used to force other items of information to be displayed.
–sk, –skip-keypress
When the –check command option is used, after certain sections of tests, the user will be prompted to press the return key
in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.
