如何在终端查看图片？
前提是linux系统或者是mac系统，windows系统可以不要往下看了。
先上效果：
imgcat-result.png
再上步骤：
- 在
home目录下新建一个bin目录（个人一般喜欢把一些脚本统一放在这里），并创建一个名为imgcat的文件，并将下列内容复制到文件中并保存。
#!/bin/bash
# tmux requires unrecognized OSC sequences to be wrapped with DCS tmux;
# <sequence> ST, and for all ESCs in <sequence> to be replaced with ESC ESC. It
# only accepts ESC backslash for ST. We use TERM instead of TMUX because TERM
# gets passed through ssh.
function print_osc() {
if [[ $TERM == screen* ]] ; then
printf "\033Ptmux;\033\033]"
else
printf "\033]"
fi
}
# More of the tmux workaround described above.
function print_st() {
if [[ $TERM == screen* ]] ; then
printf "\a\033\\"
else
printf "\a"
fi
}
# print_image filename inline base64contents print_filename
# filename: Filename to convey to client
# inline: 0 or 1
# base64contents: Base64-encoded contents
# print_filename: If non-empty, print the filename
# before outputting the image
function print_image() {
print_osc
printf '1337;File='
if [[ -n "$1" ]]; then
printf 'name='`printf "%s" "$1" | base64`";"
fi
VERSION=$(base64 --version 2>&1)
if [[ "$VERSION" =~ fourmilab ]]; then
BASE64ARG=-d
elif [[ "$VERSION" =~ GNU ]]; then
BASE64ARG=-di
else
BASE64ARG=-D
fi
printf "%s" "$3" | base64 $BASE64ARG | wc -c | awk '{printf "size=%d",$1}'
printf ";inline=$2"
printf ":"
printf "%s" "$3"
print_st
printf '\n'
if [[ -n "$4" ]]; then
echo $1
fi
}
function error() {
echo "ERROR: $*" 1>&2
}
function show_help() {
echo "Usage: imgcat [-p] filename ..." 1>& 2
echo " or: cat filename | imgcat" 1>& 2
}
function check_dependency() {
if ! (builtin command -V "$1" > /dev/null 2>& 1); then
echo "imgcat: missing dependency: can't find $1" 1>& 2
exit 1
fi
}
## Main

has_stdin=f

- 并对刚才的文件设置执行权限。
$ sudo chmod 777 ./imgcat
- 将
~/bin添加到环境变量中
// 用的是bash就修改.bashrc 用的是zsh就修改.zshrc
$ vi ~/.bashrc
// 添加如下内容
export PATH = $PATH:/home/yourname/bin
- 重启bash使环境变量生效，或者通过
source来使其生效
// bash
$ source .bashrc
// zsh
$ source .zshrc
