[BASH] Issue with parsing line from file
Hi,

I am trying to parse a line from a file and place the values into separate variables:

input.txt:
Code:
CreateVegaFeed-20110928-before-skip-start


this is the code i have done so far:

Code:

$input_file="input.txt"
INPUT_FILE=`cat $input_file` 

for i in $INPUT_FILE
do
    #parse current line from input file into appropriate variables 
    IFS='-';read currentJBPM time_stamp report_type skip_node start_node <<<$i

#do stuff with the variables
done

The issue is that the values in the file are not being inputted into the variables, expect for the first value: CreateVegaFeed

This is the output of the code with set -x

Code:

++ cat input.txt
+ INPUT_FILE='CreateVegaFeed - 20110928 - before - skip - start '
+ for i in '$INPUT_FILE'
+ IFS=-
+ read currentJBPM time_stamp report_type skip_node start_node
+ echo process: CreateVegaFeed
process: CreateVegaFeed
+ echo timestamp:
timestamp:
+ echo report type:
report type:
+ echo skip:
skip:
+ echo start:
start:

The output from the set -x is suggesting that you have extraneous white space in the line shown from the input file, which makes me think that the for loop is presenting one word at a time.
Is that all the output from the command as I think I'd expect the for loop to iterate a few more times.

learn gawk, it will pay off big time if this sort of issue recurs for you.
Code:
$ gawk -F- '{for(i=1;i<=NF;++i){printf "field %d: %s\n",i,$i}}'
a-b-cde - efg
field 1: a
field 2: b
field 3: cde 
field 4:  efg
^D

The field separator is a regular expression. You could handle the possible space problem with

$ gawk -F' *- *' 'gawk program that often fits on a line' input.txt

Yes but ... that doesn't actually help assign those values to variables outside the [gn]awk script, does it?

Thanks guys it was very helpful!

i figured out that it can also be done the following way:


Code:
INPUT_FILE=`cat $input_file` 

while read -r i
do
    #parse current line from input file into appropriate variables 
    read currentJBPM time_stamp report_type skip_node start_node <<<$(IFS="-";echo $i)
    #echo process: $currentJBPM
    #echo timestamp: $time_stamp
    #echo report type: $report_type
    echo skip: $skip_node
    echo start: $start_node
done <<< "$INPUT_FILE"


the values are getting stored to the correct variables. The only issue I am having is with space. Say forexample the value supposed to be stored into $skip_node contains a value such as this:

Code:

"val1 val2"


when I rund the code, val1 gets stored to $skip_node and val2 gets stored to $start_node. hence I am thinking the IFS is not being interpreted properly.

What, precisely, is the format (including spaces, tabs, etc.) of the input file?

good question
It's looking like akaballa123 needs to parse strings as a single token. Stick with gawk. And you're right, I didn't read the original question carefully.

hmm, I tried your code and I assigned the output to the necessary vartiables. but I am getting a gawk not found error:

Code:

./createlist.sh: line 63: gawk: command not found


this is the modification I made:

Code:

 set -- `gnawk -F' *- *' '{for(i=1;i<=NF;++i){printf "field %d: %s\n",i,$i}}' $INPUT_FILE`
    currentJBPM=$1
    time_stamp=$2
    report_type=$3
    skip_node=$4
    start_node=$5

sorry i put gnawk...but i did try with gawk and it did not work. I believe that my system does not support gawk. So I tried with nawk. nawk command is being recognized but the fields are not getting parsed properly.

The other thing is, I might have more than 1 line in the input file. So I want to read one line at a time, then do some work with the fields in the current line then move to the next line. So I am not sure if nawk/awk is right for me.

There are a few variations of the awk program - the original one, named, funnily enough, awk. Then there is gawk (GNU awk), also nawk (I think named for new awk). When I said [gn]awk I was trying to refer to them all as one ... too clever by half, I fear!
Keeping to awk (probably safest as most/all installs of *nix will have that).
awk, in any of it's forms will process a file, one line at a time, 'chopping' up each line into fields. This is what you seem to want. Thus, what we need to do is found out what unique character in your file denotes a 'break' between each field as you wish to see them.
From an earlier post your input file looks to have a lines set up the following:
Code:
+ INPUT_FILE='CreateVegaFeed - 20110928 - before - skip - start '

Then you mention that the 4th field (skip) can comprise two words. Things get 'confused' whrn spaces start appearing as various programs assume that a space denote a 'break' in the flow.
I think that your initial premise to use the hyphen as a field separator is going to be the best idea. That any version of awk can do for you in this sort of situation will be the ability to 'pluck out' each field, one at a time. As you are going to have to do this one line at a time we will need to 'cheat' by having each line of the file read into a variable, and then pass that variable to awk to read as standard input:
Code:
while read file_line
do
  currentJBPM=$(echo "$file_line" | awk -F\- '{print $1}')
  time_stamp=$(echo "$file_line" | awk -F\- '{print $2}')
  report_type=$(echo "$file_line" | awk -F\- '{print $3}')
  skip_node=$(echo "$file_line" | awk -F\- '{print $4}')
  start_node=$(echo "$file_line" | awk -F\- '{print $5}')
done < $input_file

I've not got a *nix box handy at the moment so that is untested.

Am really confused now . I keep getting this error:

Code:

+ '[' GPM_FIXINGS GPM_RAW_CASH = null -a null = null ']'
./createlist.sh: line 112: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH '!=' null -a null = null ']'
./createlist.sh: line 129: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH = null -a null '!=' null -a null = null ']'
./createlist.sh: line 147: [: too many arguments

./createlist.sh: line 165: [: too many arguments


The variables get assigned the proper string and everything except the if statments are working fine. I am really confused why its causing an error.

here is the code:

Code:

./createlist.sh: line 112: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH '!=' null -a null = null ']'
./createlist.sh: line 129: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH = null -a null '!=' null -a null = null ']'
./createlist.sh: line 147: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH = null -a null '!=' null -a null '!=' null ']'
./createlist.sh: line 152: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH '!=' null -a null '!=' null -a null = null ']'
./createlist.sh: line 159: [: too many arguments
+ '[' GPM_FIXINGS GPM_RAW_CASH '!=' null -a null '!=' null -a null '!=' null ']'
./createlist.sh: line 165: [: too many arguments

....


and here is the output:
