How do I insert a tab character in Iterm?
The answer was to hit control+v, then tab afterwards, not all together! Hope this helps someone.
How do I type a TAB character in PowerShell?
If it helps, you can embed a tab character in a
double-quoted string:
"`t hello"
How do you type a tab in a bash here-document?
You can embed your here doc in your script and assign it to a variable without using a separate file at all:
#!/bin/bash
read -r -d '' var<<"EOF"
coffee\t$1.50
tea\t$1.50
burger\t$5.00
EOF
Then printf
or echo -e
will expand the \t
characters into tabs. You can output it to a file:
printf "%s\n" "$var" > prices.txt
Or assign the variable's value to itself using printf -v
:
printf -v var "%s\n" "$var"
Now var
or the file prices.txt
contains actual tabs instead of \t
.
You could process your here doc as it's read instead of storing it in a variable or writing it to a file:
while read -r item price
do
printf "The price of %s is %s.\n" $item $price # as a sentence
printf "%s\t%s\n" $item $price # as a tab-delimited line
done <<- "EOF"
coffee $1.50 # I'm using spaces between fields in this case
tea $1.50
burger $5.00
EOF
Note that I used <<-
for the here doc operator in this case. This allows me to indent the lines of the here doc for readability. The indentation must consist of tabs only (no spaces).
How to put enter or return when sending text in iTerm2

How to automatically set iTerm2 tab title to the filename opened in vim?
I don't have iTerm, so I can't test this, but try adding this to your .vimrc
:
set t_ts=^[]1;
set t_fs=^G
Type CTRL-V Escape
for ^[
and CTRL-V CTRL-G
for ^G
.
Redefine tab as 4 spaces
It depends on what you mean. Do you want actual tab characters in your file to appear 4 spaces wide, or by "tab" do you actually mean an indent, generated by pressing the tab key, which would result in the file literally containing (up to) 4 space characters for each "tab" you type?
Depending on your answer, one of the following sets of
settings should work for you:
For tab characters that appear 4-spaces-wide:
set tabstop=4
If you're using actual tab character in your source code you probably also want these settings (these are actually the defaults, but you may want to set them defensively):
set softtabstop=0 noexpandtab
Finally, if you want an indent to correspond to a single tab, you should also use:
set shiftwidth=4
For indents that consist of 4 space characters but are entered with the tab key:
set tabstop=8 softtabstop=0 expandtab shiftwidth=4 smarttab
To make the above settings permanent add
these lines to your vimrc.
In case you need to make adjustments, or would simply like to understand what these options all mean, here's a breakdown of what each option means:
tabstop
The width of a hard tabstop measured in "spaces" -- effectively the (maximum) width of an actual tab character.
shiftwidth
The size of an "indent". It's also measured in spaces, so if your code base indents with tab characters then you want
shiftwidth
to equal the number of tab characters timestabstop
. This is also used by things like the=
,>
and<
commands.
softtabstop
Setting this to a non-zero value other than
tabstop
will make the tab key (in insert mode)
insert a combination of spaces (and possibly tabs) to simulate tab stops at this width.
expandtab
Enabling this will make the tab key (in insert mode) insert spaces instead of
tab characters. This also affects the behavior of theretab
command.
smarttab
Enabling this will make the tab key (in insert mode) insert spaces or tabs to
go to the next indent
of the next tabstop when the cursor is at the beginning of a line (i.e. the
only preceding characters are whitespace).
For more details on any of these see :help 'optionname'
in vim (e.g. :help 'tabstop'
)
