Replace your code :
Code:
                echo "cat > $file <<\!EnShAr!"
                cat $file
                echo "!EnShAr!"
                echo "set 'cksum $file'"
                cksum $file > temp1
                awk '/^/ {print $1}' temp1 > temp2
                echo "test \$1 =" > temp1
                more temp2 >> temp1
                echo "|| echo \$0: BAD checksum in $file >&2" >> temp1
                tr "\n" " " < temp1 > temp2
                more temp2
                echo

by (not tested) :
Code:
                CHKSUM=$(cksum $file | awk '{print $1}')
                echo "cat > $file <<\!EnShAr!"
                cat $file
                echo "!EnShAr!"
                echo "chksum=`cksum $file | awk '{print \$1}'`
                echo "test \$chksum = $CHKSUM || echo \$0: BAD checksum in $file >&2" 
                echo

Anyone know how cksum works?

hello all. I'm not asking about the algorithm - or how it goes about computing the checksum - I'm asking how it views/looks at the files it does the cksum on. For instance: Say you had a directory named "dir_A" And within this directory you had some files. So: dir_A - file1 -... (5 Replies)

cksum question

Hi there, I have a query about cksum. I'm running a script on the Unix box and in a script the cksum result differs from when I run it manually. As far as I can see the file is not being changed, is there any other times that the cksum would be different. (4 Replies)

cksum does not give me crc32

Is cksum the right command to calculate the crc32 checksum value? I tried it for a number of files now and every time the results dont match. So there is nothing wrong with the file. Also, cksum gives me an all numerical value while crc32 is alpha numeric. What am I doing wrong? Thanks (9 Replies)

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
