Shell Programming and Scripting

Hi All,

Suppose I have a file "a.doc"

It's contents are :

mos44.0 )

.....
......
.....


export TKTS_RELEASE=tkts44.0b7
......
.......


Now , I need to first search for the pattern "mos44.0 )" and then TKTS_RELEASE will be some 30 lines below(not 30 always)...

I need to go there and then modify the value of TKTS_RELEASE variable from tkts44.0b7 to tkts44.0b10.

For modifying the contents I can use sed command ...But how do I determine where the changes shud be done...The place where I change shud satisfy two conditions ...1) "mos44.0 )" and then some lines below..TKTS_RELEASE variable..

Kindly advice...Thanking in advance....

You may try this:

Code:

grep -q "mos44.0" file_name && sed 's/tkts44.0b7/tkts44.0b10/' file_name

Can you show a bit more of this file please? Is "mos44.0 )" a kind of label that marks the start of a section? Is there anything else marking a kind of end of that section ie. when replacement should be stopped/not done?

This should replace the first match of "tkts44.0b7" after "mos44.0"

Code:

awk '
/mos44.0/{f=1}
/TKTS_RELEASE=/ && f {sub("tkts44.0b7","tkts44.0b10");f=0}
{print}' file > newfile

Franklin,
Thanks a lot for your response...

I ran the command but I get this error

awk '/mos44.0/{f=1}/TKTS_RELEASE=/ && f {sub("tkts44.0b7",tkts44.0b10");f=0} {print}' bmp.config > bmp1.config
awk: syntax error near line 1

zaxxon,
FInd the file

6194 mos44.0 )

6195 prepath PATH /scme/lbin /opt/SUNWspro/bin /opt/nmake3.1.
2/bin /usr/ccs/bin/usr/add-on/unison/bin

6197 addpath MANPATH /opt/quantify/man /opt/purify/man



6221 export DSS_RELEASE=dss11.0b1
6222 export MOS_RELEASE=mos44.0b1
6223 export TSTS_RELEASE=tsts41.0b1
6224 export COM_RELEASE=com33.0b1
6225 export TKTS_RELEASE=tkts44.0b7
6226 export CCPLITE_RELEASE=ccplite1.0
6227 export TKES_RELEASE=tkes11.0b8

mos44.0 ) (mos44.0 followed by a closing bracket ) in line 6194 of the file

then TKTS_RELEASE variable in line 6225...

Need to modify this TKTS_RELAESE variable to tkts44.0b10.

TKTS_RELEASE variable will be at several places ..but I need to modify this variable only after some lines from mos44.0.

Use nawk or /usr/xpg4/bin/awk on Solaris.

Regards
