Check These Out

Exclude inserting a table from a sql import
Starting with a large MySQL dump file (*.sql) remove any lines that have inserts for the specified table. Sometimes one or two tables are very large and uneeded, eg. log tables. To exclude multiple tables you can get fancy with sed, or just run the command again on subsequently generated files.

grep for minus (-) sign
Use flag "--" to stop switch parsing

Create a directory and go inside it
$_ expands to the last argument of the last command that was executed

List docker volumes by container

sum a column of numbers

sort lines by length

Put readline into vi mode
This lets you use your favorite vi edit keys to navigate your term. To set it permanently, put "set editing-mode vi" in your ~/.inputrc or /etc/inputrc.

Get My Public IP Address

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' "{}" \;)

Show all detected mountable Drives/Partitions/BlockDevices
Yields entries in the form of "/dev/hda1" etc. Use this if you are on a new system and don't know how the storage hardware (ide, sata, scsi, usb - with ever changing descriptors) is connected and which partitions are available. Far better than using "fdisk -l" on guessed device descriptors.
