  • It handles all possible combination of the hex bytes, including NaNs, Infinities, Normalized and Subnormal Numbers... This crazy DC stuff spent me a few days to write, optimize, polish and squeeze so that it works within the tight 255 character bound... You can modify it easily for other IEEE754 numbers, say, half, double, double-extended, quadruple (I hope someone will find this useful and submit more dc code to commandlinefu!) Show Sample Output

Get AWS temporary credentials ready to export based on a MFA virtual appliance

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

New files from parts of current buffer
On command mode in Vim you can save parts of the current buffer in another file. * The 'n' value represents the first line of the new file. * The 'm' value represents the last line of the new file. * newfile.txt is the newfile. The results are similar to this command in perl: $ perl -ne 'print if n..m' in.sql > out.sql

Mount a VMware virtual disk (.vmdk) file on a Linux box
This does not require you to know the partition offset, kpartx will find all partitions in the image and create loopback devices for them automatically. This works for all types of images (dd of hard drives, img, etc) not just vmkd. You can also activate LVM volumes in the image by running $vgchange -a y and then you can mount the LV inside the image. To unmount the image, umount the partition/LV, deactivate the VG for the image $vgchange -a n then run $kpartx -dv to remove the partition mappings.

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