My scripts

VIM

Problem: Refresh tags file with jsctags instead of ctags when file changed.

Solution: Indexer plugin and ctags script of this repo. See blog post.

ducksboard.com

Problem: Show filesystem usage as gauge. See DucksFsSamplePicture.png

Script: see ducks-fs.sh and execute it by hand or create a line at your crontab with crontab -e and add following:

@hourly bash /home/hoschi/bin/ducks-fs.sh /home YOURDASHBOARDID YOURAPIKEY >/dev/null

Java

remove class name after renaming classes in IDEA:

Problem:

org.hoschi.sweetp.server.web.HooksServlet.log.info 'handle as html'

Should be:

log.info 'handle as html'

Script:

sed -i 's/^\(\s*\)\S*\(log\)/\1\2/' server/src/main/groovy/**/*.groovy

Problem: Due to its slowness, inform me when task finished.

Script: Use provided notification script to scan log of task startup.

./notifyForText  /home/user/repos/project/grails.log 'Server running. Browse to http' 'Slow server started ...' icon.png

This shows you a notification when the server started with your specified icon (optional).

X

Problem: Start new session in an existing session.

Srcipt:

#! /bin/bash
Xephyr -ac -screen 1910x1140 -br -reset -terminate 2> /dev/null :1 &
DISPLAY=:1.0
export DISPLAY=:1.0
ssh -XfC -c blowfish localhost gnome-session

ZSH

for in zsh:

for file in *.rar; unrar x ${file}
for file in *; do pwd; echo "this is a test ${file}"; done
for i in {1..5}; umount-$i;

How to generate file names:

See manual

*
- Matches any string, including the null string.
?
- Matches any character.
[...]
- Matches any of the enclosed characters. Ranges of characters can be specified by separating two characters by a -. A - or ] may be matched by including it as the first character in the list.
[^...]
[!...]
- Like [...], except that it matches any character which is not in the given set.
<x-y>
- Matches any number in the range x to y, inclusive. If x is omitted, the number must be less than or equal to y. If y is omitted, the number must be greater than or equal to x. A pattern of the form <-> matches any number.
^x
- Matches anything except the pattern x.
x|y
- Matches either x or y.
x#
- Matches zero or more occurrences of the pattern x.
x##
- Matches one or more occurrences of the pattern x.

Linux

xargs

Run command for every line, e.g. create one notification for each log output line

tail -n 0 -f /var/log/rsnapshot.log | xargs -L1 -d "\n" notify-send

Permissions

Set permission only for files or folders.

Files:

find . -type f -exec chmod 0644 {} \;

Folders:

find . -type d -exec chmod 0755 {} \;

Screen

Create screen session at startup automataically so you can always join it and never must create it. See create-screen.sh and at this to your startup routine.

ack-grep

ack-grep defaults to case sensitive search, use ack-grep -i to change this
only search for files with special type "ack-grep --type-set=groovy=.groovy --type=groovy SEARCH ."

Backup

MongoDb Collections

See backup-mongo-filing.sh

This script needs an git repository and a added file named "filing.json". You can achive this by:

mkdir filing
cd filing
git init
echo "backup" > Readme.md
git add Readme.md
git commit -m "init"
echo "foo bar" > filing.json
git add filing.json
git commit -m "add filing.json backup file"

Git

show all commits which in one branch but not in any other

''' B="branchInQuestion" bash -c 'git log --no-merges $B --not $(git for-each-ref --format="%(refname)" refs/heads/ | grep -v "refs/heads/$B") $(git branch -r | cut -d" " -f3 | grep -v "$B" )' '''
