UNIX, URGENT, Short problem

How do i change this grep command to send the header layout to either project3.df.output or project3.ui.output would you just change the "24" in the grep line to "df"? and would the out_file=project3.df.output

if [ `echo $1 | grep -c "24" ` -gt 0 ] #check if command line argument contains 24 or not

then

out_file=project2.24.out #set the out file to project2.24.out

else

out_file=project2.12.out #set the out file to project2.12.out

fi

echo "**************">$out_file #write the line to file in write mode so that file would get created or replaced

echo "">>$out_file #write the line to file in append more so that the line gets added in end of the file

echo "Student name : ">>$out_file #write the line to file in append more so that the line gets added in end of the file

echo "Project 2 CIS 129 Sec #">>$out_file #write the line to file in append more so that the line gets added in end of the file

echo $current_time>>$out_file #write the line to file in append more so that the line gets added in end of the file

echo "**************">$out_file #write the line to file in write mode so that file would get created or replaced

Explanation / Answer

Hi,

if [ `echo $1 | grep -c "24" ` -gt 0 ] #check if command line argument contains 24 or not

then

out_file=project2.24.out #set the out file to project2.24.out

else

out_file=project2.12.out #set the out file to project2.12.out

this block here is where you need to change where to direct the o/p to. in the current logic, if the command line arguement has 24 it is being sent to first file otherwise to the second, so as per your requirement to change the o/p filenames if based on same condition then it should be

if [ `echo $1 | grep -c "24" ` -gt 0 ] #check if command line argument contains 24 or not

then

out_file=project2.24.out #set the out file to project3.df.output

else

out_file=project2.12.out #set the out file to project3.ui.output
