I am trying to compare two text files and output the difference to another file.
I'm not strictly looking for differences in text but additional text at the end of one file that isn't in another, so basically comparing the file 2 against file 1 and printing any additional text to file 3.

Code

Code:

# Tool number
toolnr=`uname -n | cut -c2-`

# Log Directory Path
LOG_path="/usr/asm/atl.1001/user_data/error_logs"

# Input file names
file1="ASML_LOGBOOK.TXT"
file2="ASML_LOGBOOK_2.TXT

diff ${file1} ${file2} |grep "^<" > ${LOG_path}/LOG${toolnr}.TXT

the following is an error output when I run the script:
Error code:
> /usr/asm/atl.1001/user_data/error_logs/LOG1001.TXT^J^J^J: cannot open

Any help greatly appreciated!

It appears that you do not have permission to create /usr/asm/atl.1001/user_data/error_logs/LOG1001.TXT if it doesn't already exist, or you do not have permission to erase the current contents and write new data to that file if it does already exist. What is the output of the command:

Code:

ls -l /usr/asm/atl.1001/user_data/error_logs/LOG1001.TXT

after you get that error message?

Just out of curiosity, why do you want to remove the first character of the system's node name when creating a log file for that system?
