List of commands I find useful, changes over time

shellOneLiners.sh

#grep recursively
find . -type f -exec grep -n "stuff" {} \; -print

#count files in directory
ls -1 <targetdir> | wc -l

#put contents of one file at end of another
cat ./this-file >> ./into_this-file

# remove results of ls
rm `ls | grep -v NOTTEST`

#find command
#NOTE there must be a trailing / after the file path to search recurisvely if the / is left off the end the search will only look in that folder i believe.

find / -name foo > results.txt

# dding 2>/dev/null to the end ignores cannot read dir errors

find / -name *CECOM* > CECOMsearchResults.txt

find / -name *cecom* > CECOMsearchResults2.txt 2>/dev/null

find /data/data/BFH/ -name *1RL7* > 1RL7searchResults.txt
