How to cut multiple patterns from a file?
Hi,
I need to cut values after searching for similar patterns in a file. For example, I have the following pattern in a file: ####<Nov12 2007> <user: Vijay> <user id:123456 college:anna univ> <error code: runtime exception> I need the values for date: User: User id: College: Error code: Can somebody help me to obtain the same?

Vijay, show us what you have already in terms of your script.
This shows everyone that you've tried to apply some form of method. Otherwise, you've already referred to one method. Do a 'man cut' from the command line. Cheers, Cameron

Vijay,
A crude solution is outlined below - Note - I highly suspect that this is not the most efficient way to perform this task. ALSO!! Please, in future provide the forum with detail of your query and a sample of your code to show how far you have troubled. You'll likely get more qualified responses in return. Contents of 'thefile.txt': ####<Nov12 2007> <user: Vijay> <user id:123456 college:anna univ> <error code: runtime exception> ####<Nov13 2008> <user: Cameron> <user id:789012 college:bond univ> <error code: tux runtime exception> Script: Code:
#!/bin/ksh
while read inline
do
echo ${inline}
detail=`echo ${inline} | cut -f 1 -d ">" | cut -f 2 -d "<"`
user=`echo ${inline} | cut -f 4 -d " " | cut -f 1 -d ">"`
uid=`echo ${inline} | cut -f 3 -d ">" | cut -f 2 -d ":" | cut -f 1 -d " "`
uni=`echo ${inline} | cut -f 3 -d ">" | cut -f 3 -d ":"`
err=`echo ${inline} | cut -f 4 -d ">" | cut -f 2 -d ":" | cut -f 2- -d " "`
echo '- - - - - - - - - - - - - - - - - - - - - - - - - -'
echo ''
echo ' Detail: '${detail}
echo ' User: '${user}
echo ' User ID: '${uid}
echo ' University: '${uni}
echo ' Error: '${err}
echo ''
echo '- - - - - - - - - - - - - - - - - - - - - - - - - -'
echo ''
done < /home/cameron/thefile.txt
Code:
####<Nov12 2007> <user: Vijay> <user id:123456 college:anna univ> <error code: runtime exception> - - - - - - - - - - - - - - - - - - - - - - - - - - Detail: Nov12 2007 User: Vijay User ID: 123456 University: anna univ Error: runtime exception - - - - - - - - - - - - - - - - - - - - - - - - - - ####<Nov13 2008> <user: Cameron> <user id:789012 college:bond univ> <error code: tux runtime exception> - - - - - - - - - - - - - - - - - - - - - - - - - - Detail: Nov13 2008 User: Cameron User ID: 789012 University: bond univ Error: tux runtime exception - - - - - - - - - - - - - - - - - - - - - - - - - -
