Replace from taking from file
Hi,

I have one file. S_CHAR.cfg. Content given below.

Code:
\" abcd1234
\| abcd1235
\$ abcd1236

So it has two record per line delimited by space.

No I am looking for some help on how to replace this special charaters ( mentioned in record 1 of each line) with the values mentioned in S_CHAR.cfg file. ( 2nd record).

So for example if I have one file TEST.out with the content like

Code:
Great \"India\"
Great \"World\"
I am loving every \$ I earn.

After replacing it will look like
Code:
Great abcd1234Indiaabcd1234
Great abcd1234Worldabcd1234
I am loving every abcd1236 I earn.

Thanks in advance.

Replace them where? In the same file? What is your expected output?

If you want to replace the entire 1st field with 2nd,
Code:
awk '$1 = $2' file

Code:
awk 'NR == FNR{a[$1] = $2; next}
  {for(x in a)
    {gsub(x, a[x])};
    print}' S_CHAR.cfg TEST.out

Hi ,
Will it be performance wise good, if I take one loop and replace 1st records with 2nd globally using SED?

One problem with this. It's keeping the "\" in final output.

Output I got:
Code:
Great \a1b45cd56India\a1b45cd56
Great \a1b45cd56World\a1b45cd56
I am loving every \a1b45cd57 I earn.

Also it's replacing normal quotes(") and dollar($).
