1. Problem solved

When you need to enter many commands at a time, such as going to multiple directories at a time to delete files

The code is as follows:

Cd dir1

Rm file1.temp

Cd.. /.. / dir2

Rm-rf dir3

When you are too lazy to type a long command or simply can't remember it, such as generating a ctags

Ctags-- languages=C++-- exclude=third_party-- exclude=.git-- exclude=build-- exclude=out-R-F. tags

When you want a keyboard shortcut to do repetitive things with one click and don't bother to write a lot of scripts.

Duang~~ this tool is useful!

two。 Perceptual knowledge

This tool is a shell script, attached at the end of this article, copy the entire script source code, save it locally as rew.sh, put it under $PATH, and add chmod + x permissions.

The name of the file can be changed as you like. R e w can be typed with one left hand, and then the tab key will be .sh. I feel fine.

The complex operation mentioned earlier becomes so simple:

Go to several directories at a time to delete files, only need rew.sh d

If you want to specify the starting directory, you can also take the parameter rew.sh d dir_path

To generate ctags, only rew.sh ct is needed.

If you forget what this script does, just run crt.sh with no arguments and all the commands are listed.

3. Rational cognition

If you want to add custom commands, find the

The code is as follows:

Cmds= (xxxxx)

Just add one line to it. Each line is a parameter and an actual command, as you can see:

The code is as follows:

# defines commands here,format:

# shortcut | one space | action

Cmds= (

'w ninja-C out/Debug android_webview_apk'

'gyp build/gyp_chromium'

'd gdb-ex=r-- args out/Debug/chrome-- no-sandbox http://100.84.44.189'

'ct ctags-- languages=C++-- exclude=third_party-- exclude=.git-- exclude=build-- exclude=out-R-f. Tags'

#'e echo example to show this can be commentted'

'r ninja-C out/Debug chrome_shell_apk'

'u updateChrome'

't testChromeShellMemory'

'o openUrlInCAWShell'

)

That is, the first space is preceded by the parameter of rew.sh (shortcut key), and after the first space is the actual running command. Commands with multiple steps can be made into functions, such as:

The code is as follows:

UpdateChrome () {

Git pull

Cd third_party/WebKit

Git pull

Gclient sync-nohooks

}

If you are afraid of forgetting what the long command is used for, you can also put it in the function, and the function name should be noted or annotated.

This script can be called by other scripts, and the return value is the same as the command being replaced.

Tool script attached:

The code is as follows:

#! / bin/bash

# author liuhx 2015-03-03 http://blog.csdn.net/hursing

# if including multiple steps, combine them into function

UpdateChrome () {

Git pull

Cd third_party/WebKit

Git pull

Gclient sync-nohooks

}

TestChromeShellMemory () {

Ps= `adb shell ps | grep org.chromium.chrome.shell`

Rsss= `echo "$ps" | awk'{print $5;}'`

Echo "$rsss"

Pids= `echo "$ps" | awk'{print $2;}'`

For p in $pids; do

Adb shell dumpsys meminfo $p | grep TOTAL | awk'{print $2;}'

Done

}

OpenUrlInCAWShell () {

# $1 should be url

Adb shell am start-an android.intent.action.VIEW-n com.caw.webkit.test/.BrowserActivity-e policy UCM_CURRENT_WINDOW-d $1

}

# defines commands here,format:

# shortcut | one space | action

Cmds= (

'w ninja-C out/Debug android_webview_apk'

'gyp build/gyp_chromium'

'd gdb-ex=r-- args out/Debug/chrome-- no-sandbox http://100.84.44.189'

'ct ctags-- languages=C++-- exclude=third_party-- exclude=.git-- exclude=build-- exclude=out-R-f. Tags'

#'e echo example to show this can be commentted'

'r ninja-C out/Debug chrome_shell_apk'

'u updateChrome'

't testChromeShellMemory'

'o openUrlInCAWShell'

)

EchoHelp () {

For ((I = 0; I < ${# cmds [@]}; iTunes +)); do

Echo "${cmds [$I]}"

Done

ShName= `basename $0`

Echo-e "\ 033 [0transport1mexample: input'$shName ${cmds [0]% *}'to run'${cmds [0] # *}'\ 033 [0m"

}

If [[$#-eq 0]]; then

EchoHelp

Exit 255

Fi

For ((I = 0; I < ${# cmds [@]}; iTunes +)); do

Cmd=$ {cmds [$I]}

Shortcut=$ {cmd%% *}

If [["$shortcut" x = = "$1" x]]; then

Action=$ {cmd#*}

Echo-e "\ 033 [033 / 033 [033 / 033]

# skip shortcut

Shift 1

Eval $action $@

Exit $?

Fi

Done

# if no cmd matched, echoHelp

EchoHelp
