Help in adding a data after a particular line of data in a file.

Hi.. I'm into a bump after trying to solve this prob.. i've a file with contents like below.

 <blankline>
'pgmId'             : 'UNIX',
'pgmData'          : 'textfile',
'author'             : 'admin',
.......

Now i'm trying to insert a new data after pgmId. so the final output will be like:

<blankline>
'pgmId'             : 'UNIX',
'moduleId'         : 'DEFAULT',
'pgmData'          : 'textfile',
'author'             : 'admin',
.......

I tried to fix this with a sed command like:

sed  "/pgmId/{G;}/" ./tempFile  | sed -e "s/^$/\     'moduleId\' \: \'DEFAULT\'\,/1">>./tempFile1

But this command is replacing all the blank lines with moduleId.

could anyone help me out?
thanks in advance.

In nawk ..

$ echo $newline
'moduleId' : 'DEFAULT',
$
$ nawk -v var="$newline" '/.pgmId/{print $0"\n"var}!/.pgmId/' infile
 
'pgmId' : 'UNIX',
'moduleId' : 'DEFAULT',
'pgmData' : 'textfile',
'author' : 'admin',

Hi,

A quick search in this forum for "sed insert line after text" led to this sed.. Add new line after finding text

$ echo "'pgmId' : 'UNIX',
'pgmData' : 'textfile',
'author' : 'admin'," | sed "/pgmId/ a\'moduleId':'DEFAULT'"

'pgmId' : 'UNIX',
'moduleId':'DEFAULT'
'pgmData' : 'textfile',
'author' : 'admin',

Hi michaelrozar17

while using this

sed 's/pgmId.*$/&\nnew_data/' inputfile

i'm getting the following error:

 sed: Function /pgmId/ a\'moduleId':'DEFAULT' cannot be parsed.

for all the answers given above, i'm able to add just moduleId default..

I wanted to add the line as

'moduleId'   : 'DEFAULT',

the error i'm getting is that the above said line cannot be parsed

Ok..try as

sed "s/pgmId.*$/&\n'moduleId':'DEFAULT',/" inputfile
