Preserve leading white space
I have about 350 programs in which I have to add 2 lines; one before and one after a specfic line.
The following script does the job except that I lose the indentation.
Code:
#!/usr/bin/bash                                                        
while read line                                                        
do                                                                     
        line1=$line                                                    
        if [ "${line1:0:4}" = "@1,0" ]                                 
        then                                                           
        echo "if file (\"/u2/email/eps/\"+alltrim(writer)+\".eps\")"   
        echo "$line"                                                   
        echo "endif"                                                   
        else                                                           
        echo "$line"                                                   
        fi                                                             
done
