Concatenate some of the rows...
i have a file as below and i need to load it into oracle. The problem is, some of the rows are in 2 lines.

Code:
 
123456_PosWlist -----            -----            IN 0/0
123456_PosWListRpt   -----            -----            IN 0/0
123456_PosWListCSV
                      -----            -----            IN 0/0
123456_PosWlist_S1CSVBox   -----            -----            IN 0/0
123456_PosWList_S1CSV    -----            -----            IN 0/0
123456_PosWList_S1PubCSV -----            -----            IN 0/0

for example,
Code:
123456_PosWListCSV

if you're not *too* bothered about whitespace:

Code:
#   tr -s " " "\n"  < infile  | paste - - - - -
123456_PosWlist -----   -----   IN      0/0
123456_PosWListRpt      -----   -----   IN      0/0
123456_PosWListCSV      -----   -----   IN      0/0
123456_PosWlist_S1CSVBox        -----   -----   IN      0/0
123456_PosWList_S1CSV   -----   -----   IN      0/0
123456_PosWList_S1PubCSV        -----   -----   IN      0/0

Hi Panyam...

awk version shows following error...

Code:
bash-2.03$ more aaa.txt
  35111_RetrievalAppendXmitTrig
                             -----            -----            OI 0/0

bash-2.03$ awk 'NF==1 {p=$0;next} {$0=p$0;print;p=""}' aaa.txt

Use gawk/nawk. The same worked for me.

Hi Panyam,

It worrs with nawk. But it works only if the file contains one row. If i have data as below.

Code:
123456_PosWListCSV
                      -----            -----            IN 0/0
123456_PosWlist_S1CSVBox   -----            -----            IN 0/0
123456_PosWList_S1PubCSV 
                      06/17/2008 13:25            06/17/2008 13:47            IN 0/0

The above awk command is not working.

It should come like...

Code:
123456_PosWListCSV   -----            -----            IN 0/0
123456_PosWlist_S1CSVBox   -----            -----            IN 0/0
123456_PosWList_S1PubCSV  06/17/2008 13:25            06/17/2008 13:47            IN 0/0
