create a copy of a video file without the audio tracs
This works in Mac OS X (10.6.2) (natively comes with curl)
usage: currency_convert $1(amount) $2(from_denomination) $3(to_denomination)
This provides a list of shared object names (sonames) that are exported by a given tree. This is usually useful to make sure that a given required dependency (NEEDED entry) is present in a firmware image tree.
The shorter (usable) version for it would be
$ scanelf -RBSq -F "+S#f"
But I used the verbose parameters in the command above, for explanation.
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
If you omit the function name, the command will display all definitions
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"
}
Instead, install apt-get install secure-delete and you can use:
-- srm to delete file and directory on hard disk
-- smem to delete file in RAM
-- sfill to delete "free space" on hard disk
-- sswap to delete all data from swap
HDMI-1 is the interface in the example, which can be obtained just by typing xrandr and surfing through the output. There are a hell lot of configurations that can be done but I prefer auto because it works in most cases.

Grep for expression globally, list files and positions. "Hirn" is a nice german crib meaning "Brain". :-) Afterwards you can edit the line you want with "vi ./p_common/common_main.pbt +1550"
