  • I don't know if you've used sqsh before. But it has a handy feature that allows you to switch into vim to complete editing of whatever complicated SQL statement you are trying to run. But I got to thinking -- why doesn't bash have that? Well, it does. It's called '|'! Jk. Seriously, I'm pretty sure this flow of commands will revolutionize how I administer files. And b/c everything is a file on *nx based distros, well, it's handy. First, if your ls is aliased to ls --color=auto, then create another alias in your .bashrc: alias lsp='ls --color=none' Now, let's say you want to rename all files that begin with the prefix 'ras' to files that begin with a 'raster' prefix. You could do it with some bash substitution. But who remembers that? I remember vim macros because I can remember to press 'qa' and how to move around in vim. Plus, it's more incremental. You can check things along the way. That is the secret to development and probably the universe. So type something like: lsp | grep ras Are those all the files you need to move? If not, modify and re-grep. If so, pipe it to vim. lsp | grep ras | vim - Now run your vim macros to modify the first line. Assuming you use 'w' and 'b' to move around, etc., it should work for all lines. Hold down '@@', etc., until your list of files has been modified from ras_a.h ras_a.cpp ras_b.h ras_b.cpp to: mv ras_a.h raster_a.h mv ras_a.cpp raster_a.cpp mv ras_b.h raster_b.h mv ras_b.h raster_b.cpp then run :%!bash then run :q! then be like, whaaaaa? as you realize your workflow got a little more continuous. maybe. YMMV.

  • This script will list all the files in the tarballs present on any folder or subfolder of the provided path. The while loop is for echoing the file name of the tarball before listing the files, so the tarball can be identified


    -2
    find <path> -name "*.tgz" -or -name "*.tar.gz" | while read file; do echo "$file: "; tar -tzf $file; done

  • This command will copy a folder tree (keeping the parent folders) through ssh. It will: - compress the data - stream the compressed data through ssh - decompress the data on the local folder This command will take no additional space on the host machine (no need to create compressed tar files, transfer it and then delete it on the host). There is some situations (like mirroring a remote machine) where you simply cant wait for a huge time taking scp command or cant compress the data to a tarball on the host because of file system space limitation, so this command can do the job quite well. This command performs very well mainly when a lot of data is involved in the process. If you copying a low amount of data, use scp instead (easier to type) Show Sample Output

  • Strips comments from at least bash and php scripts. Normal # and // as well as php block comments removes all of the: empty/blank lines lines beginning with # lines beginning with // lines beginning with /* lines beginning with a space and then * lines beginning with */ It also deletes the lines if there's whitespace before any of the above. Add an alias to use in .bashrc like this: alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"

Copy from host 1 to host 2 through your host

Display rows and columns of random numbers with awk
Displays six rows and five columns of random numbers between 0 and 1. If you need only one column, you can dispense with the "for" loop.

network interface and routing summary

Get the full path of a bash script's Git repository head.
Rather than complicated and fragile paths relative to a script like "../../other", this command will retrieve the full path of the file's repository head. Safe with spaces in directory names. Works within a symlinked directory. Broken down: $cd "$(dirname "${BASH_SOURCE[0]}")" temporarily changes directories within this expansion. Double quoted "$(dirname" and ")" with unquoted ${BASH_SOURCE[0]} allows spaces in the path. $git rev-parse --show-toplevel gets the full path of the repository head of the current working directory, which was temporarily changed by the "cd".
