Replace underscores with spaces in filenames and dirnames, recursively into subdirs.

Everyone wants to take spaces out of filenames. Forget that. I want to put them back in. We've got tools and filesystems that support spaces, they look better, so I'm going to use them. Because of how find works I find I need to run this multiple times, if it's renaming subdirs. But it can be re-run without issues. I got this version of the command from a comment in this underscore-generating command. http://www.commandlinefu.com/commands/view/760/find-recursively-from-current-directory-down-files-and-directories-whose-names-contain-single-or-multiple-whitespaces-and-replace-each-such-occurrence-with-a-single-underscore. All I did was change the regex. Show Sample Output
This is sample output - yours may be different.
```
File_Name_CD1.flac
File_Name_CD2.flac
File_Name_CD3.flac

Changes into ...

File Name CD1.flac
File Name CD1.flac
File Name CD1.flac
```

Rename many files in directories and subdirectories

This is probably overkill, but I have some issues when the directories have spaces in their names. The find . -type d -print0 | while read -d $'\0' dir; do xxx; done loops over all the subdirectories in this place, ignoring the white spaces (to some extend). cd "$dir"; echo " process $dir"; cd -; goes to the directory and back. It also prints some info to check the progress. find . -maxdepth 1 -name "*.ogg.mp3" -exec rename 's/.ogg.mp3/.mp3/' {} \; renames the file within the current directory. The whole should work with directories and file names that include white spaces. Show Sample Output
This is sample output - yours may be different.
```
 process ./Various
~/Music
```

find . -type d -print0 | while read -d $'\0' dir; do cd "$dir"; echo " process $dir"; find . -maxdepth 1 -name "*.ogg.mp3" -exec rename 's/.ogg.mp3/.mp3/' {} \; ; cd -; done

Recursive find and replace file extension / suffix (mass rename files)

Find recursively all files in ~/Notes with the extension '.md' and pipe that via xargs to rename command, which will replace every '.md' to '.txt' in this example (existing files will not be overwritten).

Recursive replace of directory and file names in the current directory.

This is better than doing a "for `find ...`; do ...; done", if any of the returned filenames have a space in them, it gets mangled. This should be able to handle any files. Of course, this only works if you have rename installed on your system, so it's not a very portable command.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Connect to all running screen instances

There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.

Query well known ports list

Uses the file located in /etc/services

Direct auto-complete in bash

list block devices

Shows all block devices in a tree with descruptions of what they are.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Print lines in a text file with numbers in first column higher or equal than a value

A text file contains thousands of numbers. This command prints lines were the number is greater or equal than a specified value (134000000).

finding cr-lf files aka dos files with ^M characters

Looking for carriage returns would also identify files with legacy mac line endings. To fix both types: $ perl -i -pe 's/\r\n?/\n/g' $(find . -type f -exec fgrep -l $'\r' "{}" \;)

ROT13 using the tr command

Rename files to be all in CAPITALS

Simple bash/ksh/sh command to rename all files from lower to upper case. If you want to do other stuff you can change the tr command to a sed or awk... and/or change mv to cp....
