I have a very heavy file and with binwalk I have to extract only one file type (png) and obviously given the size of the file I can not extract all.
I tried to do binwalk -D 'png image:png' [filename] but continue to extract all files.
How can I make binwalk extract only the files I want?
You just have to use --rm :
binwalk --dd='png image:png:' [filename] --rm
Empty files will still be created but you can just ignore / delete them.

I've got a number of CSV files saved with pandas as zip files. I'd like to read them into KDB without having to manually unzip them in a terminal beforehand.
It looks like KDB supports compression:
https://code.kx.com/q/kb/file-compression/
But I can't figure out how to get it to decompress it. What I read in looks like the literal zip file.
How do I read a zipped CSV file in KDB?
Named pipes can be used for this purpose
https://code.kx.com/q/kb/named-pipes/
q)system"rm -f fifo && mkfifo fifo"
q)system"unzip -p t.zip t.csv > fifo &"
q)trade:flip `sym`time`ex`cond`size`price!"STCCFF"$\:()
q).Q.fps[{`trade insert ("STCCFF";",")0:x}]`:fifo
I'm currently trying to use exiftool on Windows command prompt to read meta data from multiple files, then output to a single text file.
The exact command I last tried looked like this:
exiftool.exe -FileName -GPSPosition -CreateDate -d "%m:%d:%Y %H:%M:%S" -c "%d° %d' %.2f"\" -charset UTF-8 -ext jpg -w _Coordinate_Date.txt S:\Nick\Test\
When I run this, I get 7 individual text files with the content for one corresponding file in each of them. However, I simply want to output all of it to one single text file. Any help is greatly appreciated
The -w (textout) option can only be used to write multiple files. It is not meant to be used to output to a single file. As per the docs on -w:
It is not possible to specify a simple filename as an argument -- creating a single output file from multiple source files is typically done by shell redirection
Which is what you're doing with the >> ./output.txt part of your command. The -w _Coordinate_Date.txt isn't doing anything and I would think throw an Invalid TAG name: "w _Coordinate_Date.txt" error if quoted together like that as it gets treated as a single arugment. The -w option requires two arguments, the -w and either an extension or a format string.
I actually figured it out, if you wrap the entire -w _Coordinate_Date.txt command in quotations and append it to a file, you can throw all of the output into one text file.
i.e. "-w _Coordinate_Date.txt >> ./output.txt"
I'm trying to remove a list of msgids from a .pot file. Is there some commandline tool which is capable of doing something like
msgdelete "foo*" bar.pot
I've found a workaround but it feels very dirty. Here I want to remove all msgids which consist of a single number or char:
msggrep -Ke '^[0-9a-z]$' project.pot > remove.po
msgcomm -u project.pot remove.po -o project.pot
rm remove.po
I am using JasperStarter to create pdf from several jrprint files and then print it using JasperStarter functtions.
I want to create one single pdf file with all the .jrprint files.
If I give command like:
jasperstarter pr a.jprint b.jprint -f pdf -o rep
It does not recognise the files after the first input file.
Can we create one single output file with many input jasper/jrprint files?
Please help.
Thanks,
Oshin
Looking at the documentation, this is not possible:
The command process (pr)
The command process is for processing a report.
In direct comparison to the command for compiling:
The command compile (cp)
The command compile is for compiling one report or all reports in a directory.
occasionally I run a backup of my phpbb forum files from the Shell command line:
zip -r forum_backup ~/public_html/forum/*
I'd like to add date elements to the file name, so that the zip file created is automatically formed as
forum_backup_05182013.zip
any other similar current date format would also be acceptable
now=$(date +"%m%d%Y")
zip -r forum_backup_$now ~/public_html/forum/
Without defining a variable first you can do it in one line with
zip -r "forum_backup_$(date +"%Y-%m-%d").zip" filelist
As taken from here
the following shell command, change the format as you want
FORMAT="%Y%m%d"
_DATE=$(date +"$FORMAT" )
zip -r "forum_bakcup_${_DATE}" ~/public_html/forum/*
