Place 2 digit letter in a file at particular place

[pk1974]

Hi

Can anyone help me to place a code of 2 digits from a file and place into another file at a particular position

[Bob E Campbell]

Sure, but you will need to give us more information. Is this binary data? Is the position determined by offsets or data? By two digit letter do you mean a single multi-byte character?

Example file snippets would make this a simple matter for many in the forums.

Do you want to insert or replace the 2 chars?
Is it a particular position in every record or in one place in the file?

thanks for ur reply

for everyfile we have to place a 2 digit code like"01" at position 31 and 32 at line 1

[Bob E Campbell]

If you mean to do an insert try:

sed -e "1 s/\(.\{32\}\)/\1XX/" < YourFile

And if you meant to replace try:

sed -e "1 s/\(.\{30\}\)../\1XX/" < YourFile

That one is not working, please check my request

This is line number 1

00XXXXXXXXXX20081110XXXXXXXXXX00TT1

I want to place 45 after TT1 that position is 35 and 36

after placing it should be look like this

00XXXXXXXXXX20081110XXXXXXXXXX00TT145

could you please help me

Thought I would decipher this for you.

# sed -e "1 s/\(.\{30\}\)../\1XX/" < temp

"1" - This is the line to edit. It can be given a specific number, a range "2,7" or a pattern to match "/Customer/".

".\{30\}" - This will match any 30 characters and will work for our use. If we put a "^" at the start it would lock it to the first 30 characters on the line.

"\( \)" - These tell sed to remember the characters matched for use in the replacement string.

"." - This matches any single character

"\1" - The first (and only) pattern saved above

"XX" - Your special chars

OK, several examples in case you asked the wrong question.

By position:

# sed -e "1 s/\(.\{35\}\)/\145/" < temp
00XXXXXXXXXX20081110XXXXXXXXXX00TT145

By TT1:

# sed -e "1 s/TT1/TT145/" < temp
00XXXXXXXXXX20081110XXXXXXXXXX00TT145

By end of line:

# sed -e "1 s/$/45/" < temp
00XXXXXXXXXX20081110XXXXXXXXXX00TT145
