How can I find and change.....

[jarod]

Hi,
could please help me to find and change specific char.

My file is like that:

:12:xxx vvv ggg
:13:ggggggg zzzzzz
:35B:aaaaa bbbbbbbb
ccccc:dddddd
:33B:ttttt zzzzzzz

How can I find the char : between ccccc and dddddd and change it to a /

Thanks for your help
Jarod

Hi, jarod!

If I properly understood your problem, maybe you can match entire row of pattern /ccccc:dddddd/ and print "ccccc/dddddd" instead old row:

awk '/ccccc:dddddd/ { print "ccccc\/dddddd"; next }  { print }' inputfile

Bye!

Hi KP,
First of all thanks for your quick answer.

The problem is that in the file there are more than one line wich start with :35B: and I don't know what I can find before and after the char :

So the change must consider all line wich start with :35B:

Thanks
Jarod

Hi again, Jarod!

You can also use sed for this kind of problems:

sed -e 's/:35B:/\/35B\//g' file.txt

God bless you! Bye!

Salut KP,

I don't want to change :35B: but only the next : wich found between 2 string.

Thanks,
Jarod

If I quite understood your problem, maybe this gawk solution helps you:

C:\TEMP\awk>awk -F: '{ if (sw) { gsub(/:/,"\/"); print; sw = 0; next }}
$2 ==  "35B" { sw = 1 }  { print }' inputfile

This gawk program changes line after line with pattern '35B'.

Bye!

Oops,

Previos gawk program changes line after line which the 2nd field has value '35B'.

Bye again!
