Collection of random scripts that make my life in the Linux console way simpler.

Do not expect readability, stability, compatibility, portability, applicability, or survivability.

Most of them are just a verbatim dump of what I'm using on my system(s). Simply sharing them to give back to the community. Written in shell, bash, python and even php.

This section is included because it may be impossible to understand what some of they do by simply looking at them.

• aslr-off <command> launches command with ASLR disabled
• awkrc swaps first and second column (and removes the rest)
• awksum [n] outputs the decimal sum of first column (or n^th) column
• deflate inflates deflated content
• htmlentitydecode decodes HTML entities
• json2csv converts json input to csv output
• melodyping [params] <dest> pings dest and produces a sound on every packet received (pitch is latency depenedent)
• melodywatch <command> watch command and procude audible alert when output changes
• onlyascii filter out non-printable characters
• pdf2image <file.pdf> [out.pdf] 'print-and-scan' file.pdf document, save as out.pdf; pauses in the middle so edits can be done if needed
• pdfbooklet <file.pdf> prepares file.pdf to be printed as a book (two-sided); BOOK1-file.pdf is to be printed on one side and BOOK2-file.pdf on the other side of the paper stack
• pdf.clear-meta <file.pdf> removes metadata from file.pdf overwriting it
• pdf.convert_from_iOS converts iOS Keynote generated pdf file so that loading it doesn't take forever; overwrites original
• range <n> generates all n-digit numbers from 000...000 to 999...999; like seq but prints "004" instead of "4"
• renamelinks <perlexpr> <files ..> takes rename syntax but changes the symlink string instead of renaming the file
• rir2nmap converts whois inetnum/NetRange/etc. output (e.g. "8.0.0.0 - 8.127.255.255") to format that nmap can take as a parameter (e.g. 8-8.0-127.0-255.0-255)
• selcol <n1,n2,n3> prints only selected columns (alias for awk '{print $n1,$n2,$n3}')
• sftp-once [params] [user@]<host> makes sftp connection to host without verifying or saving keys
• shqueue asynchronously executes long-running shell commands one-by-one; first instance will become the server, the others will be clients
• skiprows <n> skip first n rows
• sortuniq [-c] much faster (to my own surprise) replacement for sort | uniq; removes duplicate lines without actually sorting them
• ssh-once [params] [user@]<host> makes ssh connection to host without verifying or saving keys
• ssh-once-legacy [params] [user@]<host> makes ssh connection to host without verifying or saving keys; supports obsolete algorithms
• striptags removes HTML tags
• toplines [-n] show most prevalent lines and their count; prints top n lines
• unbuffer <command> disables output buffering for commands that can't do that natively
• urldecode decodes URL encoded characters (RFC3986)
• xargs1 [options] <command> executes command with parameters taken from input; alias for xargs -L1
• xident prints the most useful info about an X window selected with your mouse
