Adding a new line after a specific line with sed
Hi All,

My requirement is to add a specific line in a file after a certain line that contains 'setenv'

the existing code is like
Code:
setenv SEQFILES "/ConvWrk/inteng03/alltars/bnymais1"

LIBDEF scope='JOB' type='PGM' dataset='SUNAR.PJ90000P.JOBLIB' lib='/invest1/io09100/bnymport:/invest1/io09100/mbm:/bnymasia/invest1:'

I am using
Code:
sed 's!.*setenv.*!&/\nsetenv PRICESEQ "/invest1/iomaint/seqfiles/SHARED.CARDLIB"!' T3 > ${ORIG_JOB}_S

i am expecting the code to be

Code:
setenv SEQFILES "/ConvWrk/inteng03/alltars/bnymais1"
setenv PRICESEQ "/invest1/iomaint/seqfiles/SHARED.CARDLIB"

LIBDEF scope='JOB' type='PGM' dataset='SUNAR.PJ90000P.JOBLIB' lib='/invest1/io09100/bnymport:/invest1/io09100/mbm:/bnymasia/invest1:'

however its not taking the next line
its getting appended in the same line itself.

my output :
Code:
setenv SEQFILES "/ConvWrk/inteng03/alltars/bnymus1"/nsetenv PRICESEQ "/invest1/iomaint/seqfiles/SHARED.CARDLIB"

LIBDEF scope='JOB' type='PGM' dataset='SUNAR.PJ90000P.JOBLIB' lib='/invest1/io09100/bnymport:/invest1/io09100/mbm:/bnymasia/invest1:'

i know i am commiting a silly mistake.. Kindly rectify.

Hello gotamp,

Could you please try following and let me know if this helps you.
Code:
awk -vLINE="setenv PRICESEQ \"/invest1/iomaint/seqfiles/SHARED.CARDLIB\"" '/^setenv SEQFILES/{print $0 ORS LINE;next} 1'  Input_file

Output will be as follows.
Code:
setenv SEQFILES "/ConvWrk/inteng03/alltars/bnymais1"
setenv PRICESEQ "/invest1/iomaint/seqfiles/SHARED.CARDLIB"
 
LIBDEF scope='JOB' type='PGM' dataset='SUNAR.PJ90000P.JOBLIB' lib='/invest1/io09100/bnymport:/invest1/io09100/mbm:/bnymasia/invest1:'

Thanks,
R. Singh

Hello gotamp,

Yes, mind and soul's satisfaction is very much important. So here is a sed solution which may help you. Also I tested this in GNU sed only.
Code:
sed  '/setenv SEQFILES \"\/ConvWrk\/inteng03\/alltars\/bnymais1\"/ a setenv PRICESEQ \"/invest1/iomaint/seqfiles/SHARED.CARDLIB\""'   Input_file

Output will be as follows.
Code:
setenv SEQFILES "/ConvWrk/inteng03/alltars/bnymais1"
setenv PRICESEQ "/invest1/iomaint/seqfiles/SHARED.CARDLIB""
  
LIBDEF scope='JOB' type='PGM' dataset='SUNAR.PJ90000P.JOBLIB' lib='/invest1/io09100/bnymport:/invest1/io09100/mbm:/bnymasia/invest1:'

Thanks,
R. Singh

The sed in post#1 works for me. Might be a sed version incompatibiity, or, you are on a system that doesn't have \n as the line terminator.

Unix sed needs a backslash-newline in the sed code. It can be done with the s command, but the a command is more elegant
Code:
sed '\!setenv! a\
setenv PRICESEQ "/invest1/iomaint/seqfiles/SHARED.CARDLIB"' T3 > ${ORIG_JOB}_S
