  • apt-get upgrade with bandwidth limit

    in Debian-based systems apt-get could be limited to the specified bandwidth in kilobytes using the apt configuration options(man 5 apt.conf, man apt-get). I'd quote man 5 apt.conf: "The used bandwidth can be limited with Acquire::http::Dl-Limit which accepts integer values in kilobyte. The default value is 0 which deactivates the limit and tries uses as much as possible of the bandwidth..." "HTTPS URIs. Cache-control, Timeout, AllowRedirect, Dl-Limit and proxy options are the same as for http..."


    2
    sudo apt-get -o Acquire::http::Dl-Limit=20 -o Acquire::https::Dl-Limit=20 upgrade -y

  • Probably, most frequent use of diff

    This form is used in patches, svn, git etc. And I've created an alias for it: alias diff='diff -Naur --strip-trailing-cr' The latter option is especially useful, when somebody in team works in Windows; could be also used in commands like svn diff --diff-cmd 'diff --strip-trailing-cr'... Show Sample Output


    4
    diff -Naur --strip-trailing-cr

  • svn diff colorized

    If colordiff utility installed, it is sometimes handy to call this command. Of course, you should create an alias for it. E.g. svndiff.


    1
    svn diff --diff-cmd="colordiff"

  • rsync instead of scp

    The command copies a file from remote SSH host on port 8322 with bandwidth limit 100KB/sec; --progress shows a progress bar --partial turns partial download on; thus, you can resume the process if something goes wrong --bwlimit limits bandwidth by specified KB/sec --ipv4 selects IPv4 as preferred I find it useful to create the following alias: alias myscp='rsync --progress --partial --rsh="ssh -p 8322" --bwlimit=100 --ipv4' in ~/.bash_aliases, ~/.bash_profile, ~/.bash_login or ~/.bashrc where appropriate. Show Sample Output


    17
    rsync --progress --partial --rsh="ssh -p 8322" --bwlimit=100 --ipv4 user@domain.com:~/file.tgz .
