list files recursively by size

easy C shell math calculators
allows simple C shell access to the power of bc - never could figure out how to do the same thing with Bash - that's why I use tcsh most of the time.

Rename .JPG to .jpg recursively
This command is useful for renaming a clipart, pic gallery or your photo collection. It will only change the big caps to small ones (on the extension).

Remove grep itself from ps
When you 'ps|grep' for a given process, it turns out that grep itself appears as a valid line since it contains the RE/name you are looking for. To avoid grep from showing itself, simply insert some wildcard into process' name.

Create sqlite db and store image
Creates a simple sqlite db (img.db) inserts /tmp/Q.jpg on base64 an recorvers it as /tmp/W.jpg

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Number of commits per day in a git repository

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'...

create dir tree
create tree of dir's in one command
