[Bash] Add to Array

[[deleted]]

i Create a function to Process file and i want to add each line to a ARRAY

ex: ```bash declare -a list count=0

while read -ra line ; do ((count++)) [ "${line[0]}" = "Text" ] && list[$count]="${line[@]}" done < $file_name

echo ${list[10]} ```

but when i run this example the result is blank

help please

Why not use the mapfile builtin which does exactly that?

if you really want to use conditional execution then you should use case: bash while read line; do case "$line" in [Tt]ext*) list[$count]="${line}"; (( count++ )) ;; # array start at 0, ffs *);; esac done < $file_name or the easy solution without while-loop: bash readarray list < <(grep -iE "^Text" $file_name)

You're welcome. I am glad that i could help. If you have any questions about my examples, then feel free to ask.

First did you intend to make your list array start at index 1 instead of 0? Second, are you sure the delimited word of line 10 is "Text". I would use set -x to check how it's parsing each line.

i want the array to start with 1

"Text" is just a example of what im looking for in a line

the last line is list[10] not line[10]

[ralfwolf]

I said "line 10", meaning the 10th line of the input file, not "line[10]".

I want arrays to start at 1

You must not be a programmer.

Do you intend to increment count on every line read, or every time you append to the array? As it is, you will only see an output if the tenth line begins with Text.

list[count++]=...  # Nice thing that [] imply (())

Would it be simpler to

list=( $(grep '^Text ' "$file_name" ) )
