4975|16|
49038|6|
53560|7|
135115|8|
178857|9|

Now I want to replace second column with respective tag as per the value

0------- Success
1------- Failure
10------ unknown
.

.

and lastly make a single files that contains output as

736645|Success|
13879|Failure|
495563|Unknown|
127933|etc.|
4975|etc|

Try this,

awk -F"|" 'BEGIN {
        error[0] = "Success"
        error[1] = "Failure"
        error[2] = "Fail"
        error[3] = "Error3"
        error[4] = "Error4"
        error[5] = "Error5"
        error[6] = "Error6"
        error[7] = "Error7"
        error[8] = "Error8"
        error[9] = "Error9"
        error[10] = "Unknown"
}
{if (error[$2]){print $1 FS error[$2] FS}else{print $0}}'  inputfile

perl -i -pe '%h=qw(0 Success 1 Failure 10 unknown); /\|(\d+)\|/; $k=$1; ($h{$k})? s/\|$k\|/\|$h{$k}\|/g : s/\|$k\|/\|etc|/g;'  file

while IFS='|' read A B
do
echo "$A|${ERR[$B]}|"
done <file
result:

127933|Error14|
4975|Error16|
