tr, sed, awk, cat or scripting
I need to change all Newline caracters (\12) to Fieldseparator(\34).
tr -A '\12' '\34' <file1> file2
Replace all delete (\177) with Newline (\12)
tr -A '\177' '\12' <file2> file3
Put the name of the file first in all rows.
awk '{printf "%s\34%s\n", FILENAME,$0} file3 > file4
So far no problem. This works fine when I just need to do it with one file. Now I need to do it on 100 files. So I cant change the filename(file1>file2), and after doing all the tr commands and the awk command I need to concatenate them with:
cat * > AllFilesAfterTrandAwk
Here is an example:
file1 contains:
row1 \12
row2 \177
file2 contains:
row1 \12
row2 \177
row3 data
I need:
file1 row1 \34
file1 row2 \12
file2 row1 \34
file2 row2 \12
file2 row3 data
Does anyone have a clue?
Thanks,
MrKlint

Hi evrybody
For those who are bored I suggest exercise for tail :)
There is "csv" string:
A,B,C,D,E,G
Desired output:
| (A) A | (A,B) B | (A,B,C) C | (A,B,C,D) D | (A,B,C,D,E) E | G
There are no whitespace characters at the beginning and end of the line. (7 Replies)

combine
COMBINE(1) COMBINE(1)
NAME
combine - combine sets of lines from two files using boolean operations
SYNOPSIS
combine file1 and file2
combine file1 not file2
combine file1 or file2
combine file1 xor file2
_ file1 and file2 _
_ file1 not file2 _
_ file1 or file2 _
_ file1 xor file2 _
DESCRIPTION
combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:
and Outputs lines that are in file1 if they are also present in file2.
not Outputs lines that are in file1 but not in file2.
or Outputs lines that are in file1 or file2.
xor Outputs lines that are in either file1 or file2, but not in both files.
"-" can be specified for either file to read stdin for that file.
The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
same as "b and a". To obtain commutative behavior sort and uniq the result.
Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
