Full Discussion: Check if 10 files exist
Top Forums UNIX for Beginners Questions & Answers Check if 10 files exist Post 303002453 by siddireddy on Thursday 24th of August 2017 11:58:47 AM

This is really homework,I want to explore in shell

I did research but could not able to find the exact answer.

If i know the filenames then,I can use like below

if[-e f1.txt -a -e f2.txt -a -e f3.txt -a -e f4.txt -a -e f5.txt -a -e f6.txt -a -e f7.txt -a -e f8.txt -a -e f8.txt -a -e f9.txt -a -e f10.txt];then
cat f1.txt,f2.txt,f3.txt,f4.txt,f5.txt,f6.txt,f7.txt,f8.txt,f9.txt,f10.txt>final.txt
else
echo file not exists
fi

If the filenames like f_date,then would like give f_* but when even 1 file is available then it will create a file.

So would like to mention some where if 10 files came then only need to create new file.

atr_analysis

ATR_ANALYSIS(1p)						   User Commands						  ATR_ANALYSIS(1p)

NAME

       ATR_analysis - analyse a smart card ATR

SYNOPSIS

       ATR_analysis [ATRstring]

DESCRIPTION

       ATR_analysis is used to parse the ATR (Answer To Reset) sent by a smart card.

       The command also tries to find the card model using an ATR database stored in a text file smartcard_list.txt.

       The smartcard_list.txt file is searched in ./, /usr/local/pcsc/ and /usr/share/pcsc/ directories.

       Exemple:
	$ ATR_analysis '3B A7 00 40 18 80 65 A2 08 01 01 52'
	ATR: 3B A7 00 40 18 80 65 A2 08 01 01 52
	+ TS = 3B --> Direct Convention
	+ T0 = A7, Y(1): 1010, K: 7 (historical bytes)
	  TB(1) = 00 --> Programming Param P: 0, I: 0
	  TD(1) = 40 --> Y(i+1) = 0100, Protocol T = 0
	-----
	  TC(2) = 18 --> Work waiting time: 960 x 24 x (Fi/F)
	+ Historical bytes: 80 65 A2 08 01 01 52

	Possibly identified card:
	3B A7 00 40 18 80 65 A2 08 01 01 52
	       Gemplus GPK8000

BUGS

       Maybe many bugs since I am not a ISO 7816 expert.
