I'm developing a program that outputs all the needed data from multiple files into columns. The problem is, my program can't align multiple output into a neat column.

This is my program functions:

#!/bin/sh

function findFile
{
    while read -r LINE
    do
            find . -name "${LINE}" | grep "${LINE}" || echo "${LINE} not found"
    done < /path/to/fnames.txt > /path/to/Files.txt
}

findFile

function grepFile
{
    printf "ISA\t\tGS\tTrans\tSender ID\tReceiver ID\tINV PO Number\tASN PO Number\n"
    fmt="%-16s%-8s%-8s%-8s%-24s%-9s%-12s\n"
    while read -r LINE
    do
            gs=$(zgrep -oP 'GS.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.\K[\w\s\d]*' < $LINE | sort -u)
            isa=$(zgrep -oP 'ISA.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.\K[\w\s\d]*' < $LINE | sort)
            trans=$(zgrep -oP 'GE.\K[\w\s\d-]*' < $LINE | sort -u)
            sender=$(zgrep -oP 'ISA.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.\K[\w\s\d-]*' < $LINE | sort -u)
            receiver=$(zgrep -oP 'ISA.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.[^*]*.\K[\w\s\d-]*' < $LINE | sort -u)
            bigponumber=$(zgrep -oP 'BIG.[\w\s\d-]*.[\w\s\d]*.[\w\s\d]*.\K[\w\s\d-]*' < $LINE | sort -u)
            asnponumber=$(zgrep -oP 'PRF.\K[\w\s\d-]*' < $LINE | sort -u)
            printf "$fmt" "${isa}" "${gs}" "${trans}" "${sender}" "${receiver}" "${bigponumber}" "${asnponumber}"
    done < /path/to/Files.txt
    rm /path/to/Files.txt
}

grepFile

output: Notice those numbers that are populating the left side of the screen? That's the PO Numbers.

I want it to be like this: The same goes to INV PO Numbers

You can do this as shown:

grepFile | column -t -s $'\t' -o $'\t'

Provided the function grepFile has been modified as per my suggestions as given .

Create one more user-defined function, say, "alignCols" and pass the output from your "grepFile" function to it.

Also, modify slightly the "grepFile" function in the printf statement:

function grepFile
{

    #*************** ADD THIS ********
    t=$'\t'; # TAB char
    #*********************************

    printf "ISA\t\tGS\tTrans\tSender ID\tReceiver ID\tINV PO Number\tASN PO Number\n"

    #*************** MODIFY THIS ********
    fmt="%s\t%s\t%s\t%s\t%s\t%s\t%s\n"
    #*********************************

    while read -r LINE
    do
     # ... keep the other statements just like before #

     # ************** MODIFY printf ****************
     printf "$fmt" \
        "${isa:-$t}"         \
        "${gs:-$t}"          \
        "${trans:-$t}"       \
        "${sender:-$t}"      \
        "${receiver:-$t}"    \
        "${bigponumber:-$t}" \
        "${asnponumber:-$t}";
     # *********************************************

    done < /path/to/Files.txt
    rm /path/to/Files.txt
}

function alignCols
{
sed -e '
1i\
.TS\
tab('$'\t'');\
l l l l l l l.
$a\
.TE
' - | tbl - | nroff -Tascii -ms | grep .
}

# And then...

grepFile | alignCols

  • It discards the last Column which is the ASN PO Number and also removes the first character it queried from the PO Numbers. And unfortunately it doesn't solve the alignment of the PO numbers. It's still stuck on left side. It returns this in all lines it reads. I only posted one example here: tbl:<standard input>:4: excess data entry ASN PO Number' discarded

  • @WashichawbachaW Can you upload your file Files.txt on https://pastebin and also what script you ran .

  • no need to upload Files.txt. It only contains the names of files. What my program do is to output all the data from the contents of each of those files. See my comment on M4rty's answer.

The key here is to use the column program cf. man 1 column

It will allow you align your data as needed through a few simple option like defining a separator

You also can take a look at this question : Formatting lists with the column command in *nix

    This is in the right direction, but would be much better if it showed at least a minimal working example from the question.

  • I tried it with the code I saw from the example but still, the PO numbers are aligned in the left side of the screen. (printf "ISA GS Trans Sender_ID Receiver_ID INV_PO_NUMBER ASN_PO_NUMBER\n${isa} ${gs} ${trans} ${sender} ${receiver} ${bigponumber} ${asnponumber}\n") | column -t

  • I think the problem is with empty var which do not fill the column, you should ether try to fill blank with other characters or try with a different separator using the -s option

  • Take a look at the command in bigponumber & asnponumber zgrep -oP 'BIG.[\w\s\d-]*.[\w\s\d]*.[\w\s\d]*.\K[\w\s\d-]*' < $LINE | sort -u. It outputs all the data gathered from the content of $LINE(text.file). Most of the time it has more than a hundred output. That I see is the problem because every output of data prints in default position which is in the left side of the screen.
