# -n - less than n days (RECENT CHANGES)
# +n - more than n days (OLDER CHANGES)
# n - exactly n days
#
# ( expr ) Force precedence.
# ! expr True if expr is false.
# expr1 expr2 And (implied); expr2 is not evaluated if expr1 is false.
# expr1 -a expr2 Same as expr1 expr2.
# expr1 -o expr2 Or; expr2 is not evaluated if expr1 is true.
#
find . -ctime n # File's status was last changed n*24 hours ago

Permissions:
============
Permissions take a different meaning for directories.
read - determines if a user can view the directory's contents, i.e. do ls in it.
write - determines if a user can create new files or delete file in the directory. (Note here that this essentially means that a user with write access toa directory can delete files in the directory even if he/she doesn't have write permissions for the file! So be careful with this.)
execute - determines if the user can cd into the directory.

GIT
Normal Flow
===========
git status #Show the current status
git branch new_enchancements #Creates new Branch (Local)
git checkout new_enchancements #Switch to branch (new_enchancements)
git checkout -b new_enchancements #Creates & Switch to new_enchancements branch (Local)
git add file.php #Adding new file to git
git commit -m "Fixed,all files" #Commit the file
git push origin new_enchancements #Send to origin
git checkout --f new_enchancements #Switch to branch by force
git remote -v #git remote info
git reset filename.txt #remove a file from the current index, the "about to be committed" area,
#without changing anything else.
git reset #undo `git add .`
git -c color.ui=always #force color output
Branching
=========
Always create new branch from `development` only. Else you may conflicts raising from the branch from where you create the new.
Right-way:
==========
-------new-feature----------> 5 changes (new feature added )
/
-------/--------development----------> 0 changes (upto date with master)
\
\---hotfix-------> 2 changes (quick hotfix;go by eod )
0 ---- 1 ---- 2 ---- 3 ---- Time --->
Avoid:
=====
/---hotfix-------> 7 changes (combines with new feature)
/
-------new-feature----------> 5 changes (new feature added )
/
-------/--------development----------> 0 changes (upto date with master)
0 ---- 1 ---- 2 ---- 3 ---- Time ---->
Save changes to temp & goto other branch & come back
====================================================
$git branch #list branches #10:00 AM
development
*my-branch
master
$git status #current status #10:30 AM
modified:
abc.txt
$git stash #move changes to temp location #10:31 AM
$git checkout very_new_branch #switch to other branch #10:40 AM
$git add new.file.ext #work on other branch #02:30 PM
$git commmit -m 'Fixed issues;' #commit the changes #02:40 PM
$git checkout my-branch #back to original branch #03:00 PM
$git stash pop #get the changes from stash #03:03 PM
Revert to previous commit
=========================
git reset --hard 2454tb6
git push -f origin kmuth-branch
submodules
==========
git submodule add [-b master --depth 1] https://github.com/junegunn/fzf.git # add/init
git submodule init
git submodule update --init --recursive # update
git submodule deinit -f - fzf; rm -rf .git/modules/fzf; git rm -f fzf # remove/deinit
Revert To Original/Old - Entire directory (code base)
=====================================================
git pull ?
git stash; git fetch origin; git reset --hard origin/development #Entire directory to REMOTE_MASTER/REMOTE_BRANCH
git reset --hard df2bcfac7cabc0fd14d5c5abce22d65589e458a1 #Entire directory to particular version
Revert To Original/Old version - File level (single file)
=========================================================
git checkout -b old_is_gold #Creates & Switch to branch old_is_gold
git checkout HEAD path/to/file #Single File , from Master
git checkout d279318b40657be62accea2130ef2fdf9b150b26 -- [full/path] #Single File , from particular commit
Revert To Original/Old version - Branch level (From remote into local) (Multiple files)
=======================================================================================
git checkout -b old_local_branch #Creates & Switch to branch old_local_branch
git merge --no-ff old_remote_gold #Auto-merging from old_remote_gold to old_local_branch
git push origin old_local_branch #Push changes to origin again
Get changes from master into branch in git
============================================
git rebase master
Pick & Squash
=============
git rebase -pi development # If nothing shows on squash , try -i only
pick f7f3f6d commit 1
squash 310154e commit 2
squash a5f4a0d commit 3
git push -f origin hot-fix-branch
git rebase -pi development
#first on as pick , rest all squash
>> Refusing to squash a merge: 7daa8381fc40294b9616ebe28466a0cc2aabdca3
git status
>>rebase in progress; onto 3f688ad
>>You are currently editing a commit while rebasing branch 'kmuth-hot-fix' on '3f688ad'
git rebase --continue
#removed all the commit messages
>>Successfully rebased and updated refs/heads/kmuth-hot-fix.
git push -f origin kmuth-hot-fix
#Messed with some other branch stuff ?
git branch -D feature_branch
git checkout developemnt
git fetch origin && git pull
git checkout feature_branch
git log
# pick some recent 4-5 old commit
git rebase -i b223f604 # or git rebase -i HEAD~5
#pick/drop/squash
git push -f origin feature_branch
Undo rebase
===========
git reflog --date=iso branch #1 of 3 - REFLOG the current branch
git reset --hard 81ca2476a4 #2 of 3 - RESET to COMMIT before rebase
git push -f origin branch #3 of 3 - Just PUSH, nothing to commit/add
Example

Squashing with conflict resolved merges
=======================================
git checkout development # Move to development
git branch -D hf_with_5changes_8commits # Delete from locally
git pull origin development # Make sure git is upto date
git checkout -b hf_with_5changes_8commits # Create & checkout from development
git apply ~/5changes.patch.diff # Apply the diff (from gitlab) on
git push -f origin hf_with_5changes_8commits # Git push all the final changes
Patch apply
===========
git apply --stat ~/fix_affleck_upload.patch
git apply --check ~/fix_affleck_upload.patch
git apply ~/fix_affleck_upload.patch
git add
git commit -m "patch added"
git push origin
Copy branch to branch
=====================
git checkout -b new_branch old_branch
Example
=======
git checkout development
Switched to branch 'development'
Your branch is up-to-date with 'origin/development'.
git merge --no-ff heavy_reports
Auto-merging sonar/system/application/views/reporting.php
Auto-merging core/build/classes/core/reporting/classes/orders_report.php.php
Auto-merging core/build/classes/core/reporting/classes/KPI_Report.php
CONFLICT (content): Merge conflict in core/build/classes/core/reporting/classes/KPI_Report.php
Automatic merge failed; fix conflicts and then commit the result.
git push origin development
Everything up-to-date
Get single file from different branch from remote
=================================================
cd /data/kmuthuvel/code #go to top code level
git checkout origin/diff_branch full/path/to/file.ext
git checkout origin/smt_usage_emails core/build/classes/core/ercot/SmtDataDailyPeer.php
git checkout origin/master #to live
Clean
======
git clean -f # remove-local-untracked-files
Remove/Delete remote/local branch
=================================
git branch -d #local only
git push origin --delete #remove remote(if you know what you are doing!)
git push origin : #alias of above

`ldconfig` is a program that is used to maintain the shared library cache. This cache is typically stored in the file /etc/ld.so.cache and is used by the system to map a shared library name to the location of the corresponding shared library file.
Usage : ldconfig -v will make new programs ,ex gpg2 was able to find libksba.so.0
#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/instantclient_19_6
#validate library file for linked libs using ldd
ldd /usr/lib/instantclient_19_6/libsqora.so.19.1
