Common PASE Commands

Find

Look for a file named file.txt starting in the current directory.

find . -name file.txt

Look for files with the word 'Error' in them. First get a list of files in the current directory, pipe the results to xargs and in turn grep, and grep will search the results for "Error" in case-insensitive fashion.

find . -type f | xargs grep -i "Error"

Misc

Does a program/command exist?

$ which git
/QOpenSys/usr/bin/git

Check to see where the symbolic link points to so you know which version/implementation of a program is being run. This is especially useful for things like git because it has been delivered by PowerRuby, perzl, and now IBM. The below combines which with ls to find the destination.

$ which git | xargs ls -al
lrwxrwxrwx    1 qsys     0                82 Dec 15 2016  /QOpenSys/usr/bin/git -> /QOpenSys/QIBM/ProdData/OPS/tools/bin/git

Find version of IBM i OS. The below declares it is 7.3.

$ uname -vr
3 7
