Shell Programming and Scripting

Hello All,

I am using the below code:

Code:

#!/bin/sh
/omp/bin/TICLI "op:alarm,all" > filename

for getting command output and then putting the output into newfile but the problem is this, that not the complete output goes into newfile and the script stops.
for example: if this commands gives this output
cell 1
cell 2
cell 3
cell 4

but the newfile contains only this:
cell 1
cell 2

Please tell how i can get the complete output.

Regards,

did you try:

Code:

#!/bin/sh
/omp/bin/TICLI "op:alarm,all" | cat > filename

I am rephrasing the same question for more explanation:

Actually i run one command and i want command's output in newfile.

For this i am using below code:

Code:

#!/bin/sh
/omp/bin/TICLI "op:alarm,all" > outputfile

But problem is this that this command: op:alarm,all takes time for output but the script stops without giving the complete output in outputfile.

For Example: if this commands gives this output:
cell 1
cell 2
cell 3
cell 4

but the output file contains only this:
cell 1
cell 2

Please tell how i can get the complete output in output file.

No, the below code is still not working correctly, the output file do not contain the complete output of the command.

Actually this command takes time to generate ouput, so is there someway that the script do not ends until the complete output of the command is redirected to the output file.

Code:

#!/bin/sh
/omp/bin/TICLI "op:alarm,all" | cat > filename

Please read below for detail..

Hi! There maybe a way but we will find out until you post the code of that certain command.. otherwise we will not see what is really going with your script/command.

worth redirecting as follows ?
/omp/bin/TICLI "op:alarm,all" > outputfile 2>&1

agreed, I suspect that some of that output may be stderr and not regular stdout. The "2>&1" will catch ALL output (stderr & stdout) and send to the output file.

On that note, another method would be:

Code:

OUT=$(/omp/bin/TICLI "op:alarm,all") && echo $OUT > outputfile

This will wait until the command finshes with a return code of 0 and only then echo the variable $OUT to your file.
