-rw-r--r-- 1 kevin kevin 6.3K Nov  9 17:24 java_versions_detailed.xlsx

Answer

ls -lh | awk '{print $9 " " $5}'

^^ note the program given to the awk interpretor is wrapped in single quotes

^^^ note that the program block is wrapped in brace brackets

^^^ for the print method of AWK, note that concatenation is done via white-space seperated strings

20. Advanced Shell Scripting
ng language call AWK. A common use for awk is in field stripping. It is slightly more flexible than cut -- cat /etc/passwd | awk -F : '{print $1}' --especially where whitespace gets in the way, <span>ls -al | awk '{print $6 " " $7 " " $8}' ls -al | awk '{print $5 " bytes"}' which isolates the time and size of the file respectively. Get your nonlocal IP addresses with: ifconfig | grep 'inet addr:' | fgrep -v '127.0.0.' | \
