I am in critical need of help, Thanks a ton for your help.
I need to know how to pass the shell argument into nawk code in AIX. so that my file gets passed into that awk script and it can execute it part.
To be detail, i have more than 100 files and in those files a particular field need t o encrypt. i have a nawk script which does that part, I will share the layout here.
Code:
nawk -F"<delimiter>"'{
if (FILENAME="Mapping_file")
{
map[$1]=$2
}
else of (FILENAME = "file1")
{
k=1
while (k <= "Need to pass second argument from shell")
{
<code to encrypt>
}
}
} Mapping_file file1
I am calling this script (a.ksh) from another main script and need to pass two arguemnts (file1 in above code --> file name should the first arguemnt) and second argument in while statement
My script execution should be like this
ksh a.ksh <filename> <length> > OUTPUTFILE
finally my code should like this
Code:
nawk -F"<delimiter>"'{
if (FILENAME="Mapping_file")
{
map[$1]=$2
}
else of (FILENAME = "<filename>")
{
k=1
while (k <= "<length>")
{
<code to encrypt>
}
}
} Mapping_file <filename>
Your help on early is much appreciated. Please help me as I m in desperate need of this solution.
#!/bin/ksh
nawk -v args="$*" '
BEGIN {
n=split(args,Array," ")
first_argument = Array[1]
last_argument = Array[n]
# process your arguments here
}
{
# put your remaing code here
}
' $1 > ${@: -1}

Note : ${@: -1} is last argument, may not work with sh use ksh or bash
Assuming there's one 'Mapping_file'... Iterate through all the files to be processed with the below 'template' substituting 'file1'...
Something to start with....
Thanks you all for quick resposne. sorry I think i m not clear with my initial query.
Scripts should run like this ": ksh encrypt.ksh <input file> <Length> > Outputfile
Inputfile = different files like file1, file2 etc..
length = varies from file 1 to file2 etc..
My current script:
Code:
nawk -F"<delimiter"'{
if (FILENAME=="MAPPINGS.TXT")
{
map{$1]=$2
}
if (FILENAME=="file1 or file2")
{
while (i <= $length(parameter from script) )
{
print i,
<using map, ecnrypt the values using substr funciton to a certain length>
}
i++;
print i; (remaining records in that line)
}' MAPPINGS.TXT file1 or file2 (1st shell argument)
MAPPINGS.TXT == a single file used for all files.
file1 or file2 = Shell script first parameter
length = Shell script second parameter
NOTE: My encrypt.ksh script only consists of nawk command, I need to pass shell arguments into that nawk script.
your help is much appreciated as I m in desperate need to complete this on priority.
If so desperate, why don't you try the examples and hints given and adapt if needed? Like
Code:
if (FILENAME==ARGV[2]) {while (i <= ARGV[3] )
Unfortunately, the structures of your shell scripts and calls therein are not clear to me. Above will work if awk is called like awk '...' MAPFILE $1 $2 from within encrypt.ksh.
Shell Script Gurus,
I am writing a shell script which needs User ID's to pass as an Arguments in command line while executing.
Can this be doable? I've never done this, If you give a sample script that would be helpful, Thanks. (1 Reply)

I need to parse log files using nawk, but I'm not able to pass script input argument (date) to nawk, for example:
