Hi again. Sorry if it seems like I'm spamming the boards a bit, but I figured I might as well ask all the questions I need answers to at once, and hopefully at least get some.

Hi,
I really need some help with GREP searching...
I need to find all occurances of a file reference and remove two characters from the end of the reference. For example, here are a few lines showing the text:

I'm looking to write a script that takes a certain directory and gzips all its files that are older than 2 days. I've done some research but for the life of me, I can't even get any files gzipped. Any help would be greatly appreciated! (3 Replies)
How come grep testfile1 won't find anything in testfile1 (even though the characters sd are there in great quantity), but grep '' testfile1 will find plenty?
Do the single quotes prevent the shell from interpreting the testfile1 is interpreted as: grep *test whether or not characters sd exist*... (5 Replies)

I am new to grep and Linux and am looking to see if grep can parse out a list of lines that have a difference of more than 10 seconds between the times on each line.

capng_change_id
CAPNG_CHANGE_ID(3) Libcap-ng API CAPNG_CHANGE_ID(3)NAME
capng_change_id - change the credentials retaining capabilities
SYNOPSIS
#include <cap-ng.h>
int capng_change_id(int uid, int gid, capng_flags_t flag);
DESCRIPTION
This function will change uid and gid to the ones given while retaining the capabilities previously specified in capng_update. It is not
necessary and perhaps better if capng_apply has not been called prior to this function so that all necessary privileges are still intact.
The caller is required to have CAP_SETPCAP capability still active before calling this function.
This function also takes a flag parameter that helps to tailor the exact actions performed by the function to secure the environment. The
option may be or'ed together. The legal values are:
CAPNG_NO_FLAG
Simply change uid and retain specified capabilities and that's all.
CAPNG_DROP_SUPP_GRP
After changing id, remove and supplement groups that may come with the account.
CAPNG_CLEAR_BOUNDING
After changing the uid and gid, clear the bounding set regardless to the internal representation already setup.
RETURN VALUE
This returns 0 on success and a negative number on failure. -1 means capng has not been initted properly, -2 means a failure requesting to
keep capabilities across the uid change, -3 means that applying the intermediate capabilities failed, -4 means changing gid failed, -5
means dropping supplemental groups failed, -6 means changing the uid failed, -7 means dropping the ability to retain caps across a uid
change failed, -8 means clearing the bounding set failed, -9 means dropping CAP_SETPCAP failed.
Note: the only safe action to do upon failure of this function is to probably exit. This is because you are likely in a situation with par-
tial permissions and not what you intended.
