Search files with pattern

grep -r pattern /path 2> /dev/null

ack-grep pattern /path 2> /dev/null

Example: ack-grep "bcl2fastq*" ~/ 2>/dev/null

Notes:

Normally you wouldn't want to actually search EVERYTHING on the system. Linux uses file nodes for everything, so some "files" are not things you would want to search. For example /dev/sda is the physical block device for your first hard drive. You probably want to search the mounted file systems not the raw disk device. Also there is /dev/random which spits out random data every time you read it. Searching that doesn't make a lot of sense. The /proc file system is also problematic in your case.

Don't search at root, only search the places that might be useful. Search /home or /usr or /etc separatly. The info you are looking for is likely of a specific type, so it's likely to be in a specific folder anyway. Configuration settings should be in /etc. Your personal data files should be in /home. Limiting search to a major area like this will greatly reduce your problems with recursive greps.

Exclude problematic areas using --exclude-dir and a set of things you know you don't needlike this: grep -r --exclude-dir /proc --exclude-dir /dev --exclude-dir /tmp --exclude-dir /lost+found

-I to exclude binary

Find Select_DE_gene_basd_on_Feature in R code

ack-grep Select_DE_gene_basd_on_Feature ~/GOSJ/R/*.R

Find the file with .tiff extension

find /media/H_driver/ -name "*.tiff" 2>/dev/null

Find the file with *.bai extension and delete with asking for permission

find  /scratch/projects/bbc/Project/DI/Output_rMATS_filtered -type f -name "*.bai" -exec rm -i {} \;

Find empty directory and delete them

find /media/H_driver/PJ/Results -depth -type d -empty -delete

Find empty directory

find /media/H_driver/PJ/Results -depth -type d -empty

Setup path for R installation(add the following settings to $HOME/.bashrc, then source $HOME/.bashrc)

export PATH=$HOME/packages/bin:$PATH

export LD_LIBRARY_PATH=$HOME/packages/lib:$LD_LIBRARY_PATH

export CFLAGS="-I$HOME/packages/include"

export LDFLAGS="-L$HOME/packages/lib"

export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:$HOME/packages/include"

Check hard disk partitions and disk space on Linux

Mount ssh driver to your local Macs

1. brew install ssh-copy-id

2. ssh-keygen

3. ssh-copy-id -i .ssh/id_rsa.pub [email protected]

4. download the latest version of FUSE for OS X at the FUSE for OS X web site

5. install FUSE for OS X on my laptop by double-clicking the disk image, then double-clicking on the installation package. There is pretty standard Mac OS X stuff; it went without a hitch.

6. download the latest version of SSHFS for OS X at the FUSE for OS X web site.

7. install SSHFS by double-clicking on the downloaded file. if you ran into an issue here where Mac OS X refused to install the package because SSHFS comes from an “unidentified developer.” To get around this, you need to override the Gatekeeper in Mac OS X, which can be as simple as right-clicking on the package and selecting “Open” from the context menu.

8. Both FUSE for OS X and SSFHS were now installed.

9. mkdir ~/pegasus

10. Type the following commands

sshfs -p 22 [email protected]:/scratch/projects/bbc ~/pegasus -oauto_cache,reconnect,defer_permissions,noappledouble,negative_vncache,volname=pegasus

To mount another directory 

mkdir ~/MyHomeAtPegasus

sshfs -p 22 [email protected]:/nethome/axy148 ~/MyHomeAtPegasus -oreconnect,defer_permissions,noappledouble,volname=MyHomeAtPegasus

mkdir ~/pegasus2
sshfs -p 22 [email protected]:/projects2/med/bbc ~/pegasus2 -oauto_cache,reconnect,defer_permissions,noappledouble,negative_vncache,volname=pegasus2

mkdir HomeAtCluster
sshfs -p 22 [email protected]:/home/ay64w HomeAtCluster -oauto_cache,reconnect,defer_permissions,noappledouble,negative_vncache,volname=HomeAtCluster

mkdir ProjectAtCluster
sshfs -p 22 [email protected]:/project ProjectAtCluster -oauto_cache,reconnect,defer_permissions,noappledouble,negative_vncache,volname=ProjectAtCluster

11. if you want Unmounting, type "umount ~/pegasus"

Mount ssh driver to your local linux machine

1. Type the following commands

ssh-copy-id -i .ssh/id_rsa.pub [email protected]
mkdir /media/pegasus
sshfs [email protected]:/scratch/projects/bbc /media/pegasus

2. If you have an erro like the following:

sshfs [email protected]:/scratch/projects/bbc /media/pegasus
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option

try this:

aiminyan@aiminyan-Precision-Tower-5810:~$ sshfs [email protected]:/scratch/projects/bbc /media/pegasus -o nonempty

Make a soft link for "Dropbox (BBSR)"

ln -s "Dropbox (BBSR)" Dropbox

After finish sync, you can 
umount ~/MyHomeAtPegasus

Kill all processes that their name includes "download"

To mount H drive, edit your /etc/fstab file

note : make a smbcredentials file with your usr name and passpord included in

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
