Trimming pathnames beyond a keyword (awk, sed, ?)

I want to trim a pathname beyond a certain point after finding a keyword. I'm drawing a blank this morning.

/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java

I want to find the keyword Java, save the pathname beyond that (tsupdater), then cut everything off after the Java portion.

I'm not entirely sure what you want as output (please specify more clearly), but this command:

echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java" | sed 's/.*Java//'

results in:

/tsupdater/src/tsupdater.java

If you want the preceding part then this command:

echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java" | sed 's/Java.*//'

results in:

/home/quikq/1.0/dev/

Like I said, I was having a weird morning, but it dawned on me.

echo /home/quikq/1.0/dev/Java/TSUpdater/src/TSUpdater.java | sed s/Java.*//g

Yields

/home/quikq/1.0/dev

Lots of great tips here for chopping it up different ways though. Thanks a bunch!

I don't know if this is what you want, but you can split the pathname into two with:

echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java" | sed 'h;s/.*Java//p;g;s/Java.*/Java/'

Which outputs:

/tsupdater/src/tsupdater.java
/home/quikq/1.0/dev/Java

If you would like to save the second part into a file part2.txt and print the first part, you could do:

echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java" | sed 'h;s/.*Java//;wpart2.txt;g;s/Java.*/Java/'

If you're writing a shell script:

myvar="/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java"
part1="${myvar%Java*}Java"
part2="${myvar#*Java/}"

Hope this helps =)

take one you need:

kent$  echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java"|sed -r 's#(.*Java/[^/]*).*#\1#g'
/home/quikq/1.0/dev/Java/tsupdater

kent$  echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java"|sed -r 's#(.*Java).*#\1#g' 
/home/quikq/1.0/dev/Java

kent$  echo "/home/quikq/1.0/dev/Java/tsupdater/src/tsupdater.java"|sed -r 's#.*Java/([^/]*).*#\1#g' 
tsupdater
