I have a file which has

element * CHECKEDOUT
element \fiosapp\... .../ch_connectedhome/LATEST
element \fiosapp\... /main/LATEST -mkbranch ch_connectedhome
load \fiosapp\ConnectedHome
load \fiosapp\ConnectedHomeProject
load \fiosapp\Build

when i use the command `cat FILE_NAME |grep load |awk -F'\' '{print $2}'`
ConnectedHome
ConnectedHomeProject
Build
are getting printed but i want "fiosapp" to get printed. What do I do??

Thanks

Try

# awk -F'\' '/load/ {print $2}' FILE_NAME
fiosapp
fiosapp
fiosapp

EDIT: But I get that output even with your supplied command. What does the output of your grep command look like? What shell are you using?

awk -F\\ '/load/ {print $2}' FILE_NAME

FILE_NAME looks like a variable name, mayb you need the heading $ ---> $FILE_NAME ?

hi
I need to print once only if the output is same. In the above case i need to print fiosapp once since it is same and in the below case

element * CHECKEDOUT
element \fiosapp\... .../ch_connectedhome/LATEST
element \fiosapp\... /main/LATEST -mkbranch ch_connectedhome
load \fiosapp\ConnectedHome
load \fappa\ConnectedHomeProject
load \fasdfg\Build

I need to print fiosapp fappa fasdfg

Thanks

awk -F'\' '/load/ {print $2}' FILE_NAME | sort -u

or

awk -F'\' '/load/ {print $2}' FILE_NAME | uniq

(which do slightly different things, depending on whether you want to remove all duplicate names, or just consecutive ones)
