Replacing text/characters in vi
ok, so i have the following text to replace but it's not working. can someone please help me out:

Code:
:%s~awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'~tail -1~g

I want to replace the entire awk command with tail -1.

thanks

Try again: input, desired output and attempts so far.

The text you are trying to match contains a lot of regular expression metacharacters that require escaping. Which specific characters require escaping depends on which vi you are using, since different clones use slightly different flavors of regular expression.

The square braces are pretty good for escape if \ is not working. Just watch out for the -, ^ and ] ! If you do not need them, use a dot over them.

Hi,

Try:
Code:
$ vim -h | head -1 | sed -e 's/(.*//'
VIM - Vi IMproved 7.3
(inside Vim)
:%s~\Vawk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'~tail -1~g

Regards,
Birei

Since you haven't posted your data file, I'll assume that it looks like this -

Code:
$
$
$ cat -n f0.bak
     1  line 1 =>|awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'|<==
     2  line 2 =>|awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'
     3  awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'
     4  blah
     5  line 5 =>|awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'|<==  and =>|awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'|<==
     6  line 6 =>|awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}' and =>|awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'
     7  awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}' and awk '/[#|^[0-9][0-9]/ {split($2,s,",");a=$1 FS s[1]} /-/ {b=a} END{print b}'
     8  blah blah
$
$

I open the file shown above in Vim 7.3 and run the following editor command:

Code:
:% s/awk '.\{-}'/X/g

That's because I intend to replace the awk script awk '...' by X at all places on each line.

My file looks like this after the operation -

Code:
$
$
$ cat -n f0
     1  line 1 =>|X|<==
     2  line 2 =>|X
     3  X
     4  blah
     5  line 5 =>|X|<==  and =>|X|<==
     6  line 6 =>|X and =>|X
     7  X and X
     8  blah blah
$
$
$

HTH,

Using vim to call awk n batch seems a bit weird, as a UNIX solution.
